What vehicle(s) is/are the Override Switch designed to work on?
The Override Switch from TailgateFix.com is designed to fit and work on any GM’s trucks/vehicles that have either the MultiPro™ Tailgate for GMC or Multi-Flex™ Tailgate for Chevrolet. Currently, the vehicles with this unique tailgate are GMC’s Sierra trucks : (1500, 2500, & 3500 models), as well as, Chevrolet’s Silverado trucks : (1500, 2500, & 3500 models). GM’s newly designed HUMMER is speculated to also be coming out very soon with this tailgate on it as well.
Do I have to order a different model Override Switch depending upon which Truck model I own (1500, 2500, 3500)?
NO. The beauty of our Splitgate Override Switch from TailgateFix.com is that it is a One Size Fits All It works and installs the same on any of the designated GM trucks/vehicles whether you have a 2 inch, 2.5 inch, or 3 inch truck receiver size. Does Not Matter.
Will my warranty be affected by installing this switch?
Since our design is a true NO Splice: PLUG-N-PLAY installation that connects directly into the existing GM wiring plugs on the vehicle, then as long as you install this product as instructed, this product should NOT affect your vehicle's warranty in any way. Having said that, when purchasing any aftermarket product for a vehicle, the issuer of the Warranty, (ie: GM) has the discretion as to the installation of any aftermarket product and how it may or may not affect any warranty. However, GM created this tailgate problem issue and Tailgatefix.com has provided a high-quality solution to remedy it for all owners of these GM vehicles. We would be very surprised if GM would ever object to this being installed on these vehicles OR would allow the installation of it to affect your Warranty in any way. They have to be delighted that Tailgatefix.com has provided The Fix to this problem.
I see a competitor product on the market. How does your product compare?
Our Splitgate Override Switch is The BEST option to fix both the GMC MultiPro™ and Chevrolet MultiFlex™ Tailgate issues for the following reasons:
- Easy NO Splice Plug-n-Play Installation - TailgateFix’s Override Switch is a Plug-n-Play installation design and is easy to install. It simply plugs into the existing factory wiring in the truck’s tailgate. It can be installed by anyone, no matter what your experience level may be, by simply following our easy Step-by-Step Installation Instructions. However, if you would like, you can take our Override Switch to any GM Dealership or Automotive Service Center and have it professionally installed for you with less than an hour’s installation time;
- One Size Fits All - Our Override Switch offers Simplicity in our One-Size-Fits-All design no matter what type of Truck or Hitch Receiver size you have -vs- competitor’s model which is limited, confusing, and requires a different size switch model depending upon the size of your truck’s receiver;
- Small Design Style - Our Override Switch has a small sleek design and is installed on the truck’s receiver in a way that makes it blend in with the truck and is hardly noticeable -vs- competitor’s model is Bulky and its placement and design may cause cumbersome “ease of use” issues with truck’s receiver;
- Solid Construction - Our Override Switch is made of strong anodized Aluminum & stainless steel (not plastic), has no moving plastic parts to break, and the interior switch components are further protected by a liquid rubber sealant making it rustproof and waterproof -vs- competitor’s model is made of thin PLASTIC construction with moving plastic parts that can/will break, spring and screws that can rust, and overall will not withstand extreme weather and use conditions like ours will.
Is the adhesive bonding pad on the bottom of the Override Switch strong enough to keep Switch installed in proper placement?
The adhesive bonding pad that we use to adhere the switch to the Truck’s receiver is strong Industrial strength 3M product that is designed to adhere to a steel or aluminum surface and hold very well in temperature climates from as low as -51 degrees to as high as +250 degrees. The main thing is that when the Switch is 1st installed on the truck’s receiver, make sure that you do the following : (1) thoroughly clean your truck’s receiver with an alcohol wipe and let it dry; (2) IF you are in a colder climate area, use a heat gun or hairdryer to heat up the truck’s receiver surface to approx. 60 degrees before adhering the Override Switch to the receiver surface; (3) make sure your hands are clean of any dirt or grease; and (4) make sure that once you remove the adhesive bonding pad’s protective cover that nothing comes in contact with the sticky portion of the adhesive bonding surface until it has adhered to the truck’s receiver. Once it has properly adhered to the truck’s receiver, it has a very strong hold and will hold up nicely in basically all types of weather conditions and temperatures.
I have the Override Switch installed on my truck and I have a hitch pin inserted in the receiver of my truck so I can safely test it BUT the Inner Gate part of the Tailgate still opens as if the Override Switch is not installed. What could the problem be ?
(*) VERY IMPORTANT : Make sure that you installed the TailgateFix WIRING HARNESS correctly by having the side of the Wiring Harness that has a Tab Label that says “Passenger Side” connected to the Passenger’s side of Tailgate and the side of Wiring Harness that has a Tab Label that says “Driver Side” connected to the Driver’s side of Tailgate. IF these are connected Backwards, then, the Override Switch will NOT work correctly !!
I have the Override Switch installed on my truck and all seemed to be working BUT now when I close the Main tailgate and Inner gate back up, for some reason, the Main tailgate will now not Open ?? What could the problem be ?
This should only occur IF you have a 2022 model year GM Truck. For some reason, on 2022 model
year GM trucks, once you have installed the TailgateFix Override Switch on your truck as well as inserted a Hitch
Pin into truck’s receiver, then each time that you press the Inner tailgate button to open it, GM has something in
the inner tailgate button that causes a 1 minute, (approx 60 seconds), reset delay that keeps the Main Tailgate
temporarily locked/closed. All you have to do to clear this is EITHER : (1) Do Nothing and just wait 1 minute,
without pressing the INNER tailgate button again, to allow this reset delay to time out, and then ALL
automatically returns to normal; OR (2) you can remove the Hitch Pin from truck’s receiver and then Open &
Close the Inner Tailgate one time. Once you do this it bypasses this 1 minute reset delay and the Main tailgate is
released to open again. You can then reinsert the hitch pin back into the truck’s receiver and ALL should be back to
normal. By doing either of these options described above, this Inner tailgate open sensor delay put in tailgate
by GM on 2022 trucks ONLY should now be reset and all should operate normally.
My MultiPro or Multi-Flex inner tailgate will not open : “All I hear is a click sound when I touch the button.”
Some GMC or Chevrolet Truck owners with the MultiPro™ or Multi-Flex™ Tailgate may periodically experience an issue with their inner tailgate not releasing when the main tailgate is lowered. (ie. when you push the inner tailgate button to open it the truck’s back lights flash AND you hear a “click” sound but the inner tailgate will not open to drop down.) This is an existing issue that GM is aware of but it is not something related to or that will be caused by the installation of our Override Switch. We suggest that if you are having this issue then you should have GMC or Chevrolet look at your truck to correct this issue before installing our Override Switch.
However, After you have installed our Override Switch, if you notice that this issue is periodically occurring, below are (2) options as to how you should be able to circumvent this problem to get the inner tailgate to open properly and at the same time be able to verify that the issue is not being caused by our Override Switch and is actually the issue with the truck itself as described above :
- Remove the hitch and hitch pin from your truck’s receiver. Raise the main tailgate to its upright closed position. Then, Press and Release BOTH buttons on the tailgate at the same time. By doing this you should see both the main tailgate and the inner tailgate open and lower down at the same time.
- Remove the hitch and hitch pin from your truck’s receiver. Lower the main tailgate and then lift up just a little bit on the inner tailgate at the same time that you press and release the button to lower the inner tailgate. It should now lower as normal and not stay closed and just produce the“click” sound.
- Insert hitch and hitch pin back into truck’s receiver with our Override Switch installed. Lower the main tailgate and then press and release the button to lower the inner tailgate. The inner tailgate should not lower down at this time and you should just see the truck’s tail lights flash and NO click sound should be heard. At this point, if you hear a click sound and see the truck’s tail lights flash and #1 or #2 above worked as described, then, this confirms that our Override Switch is working properly and the issue is with the truck itself as detailed above.
This GMC Multipro™ Tailgate issue is due to the factory wiring periodically not providing enough power to release the inner tailgate and just results in the truck’s tail lights flashing and you hearing a “Click” sound which indicates that power is getting to the inner tailgate but not enough to release the latch to drop down. When our Override Switch is working properly when the switch detects that there is a hitch and hitch pin in the receiver of your truck, when you try to open the inner tailgate the inner tailgate will NOT open and the truck’s tail lights will flash but there will be NO “click” sound. If you are experiencing this described problem with your GMC truck, with or without our Override Switch installed on your truck, we would suggest that you take your truck to your GMC dealership to resolve this issue.

I installed the Override Switch, but now the Inner tailgate will not open as if the Override Switch is not working ? :
If this is occurring, the 1st thing you need to check is the wire connection plugs that you made under the truck and in the tailgate at the time of installation. Check to make sure that each of the plug connections is tightly snapped into place according to the installation instructions.
Is the Override Switch waterproof and tested against snow and ice ?
Our Splitgate Override Switch ("Switch"), is constructed of strong components designed to be resistant to all exterior weather elements. The Switch housing and bracket are made of strong anodized aluminum, with NO moving parts to break. The interior components are sealed with liquid rubber to keep all moisture away from internal connections and parts. As an added point of protection, we even apply a final coating of clear silicone to the inside top of the switch housing where wiring exits and secure it to the top of the switch housing. The wiring also has a solid exterior PVC jacket with two PVC insulated interior conductors. The Switch is connected to the truck’s wiring with insulated moisture-proof Plug-n-Play connectors designed to match the existing vehicles factory wiring, altogether designed to help keep moisture and temperature from affecting reliability.
What size Hitch Pin should I use with my Automatic model Splitgate Override Switch ?
The Automatic model of our Splitgate Override Switch is designed for a 5/8” Diameter hitch pin. You cannot use a smaller 1/2” diameter hitch pin. Required Hitch Pin Length Sizes: Trucks with a 2” receiver size requires a Hitch Pin with at least 3.625” of usable length; Trucks with a 2.5” receiver size requires a Hitch Pin with at least 4.125” of usable length, and Trucks with a 3” receiver size requires a Hitch Pin with at least 4.625” of usable length. (*) Tailgate Fix has its own line of Heavy Duty Hitch Pins that are designed to fit perfectly with our Override Switch and come in sizes to fit ALL truck receiver sizes : (2”, 2.5” and 3” Receivers).

Will Override Switch work if I insert my Hitch Pin into the truck’s receiver from either direction : ( Left-to-Right or Right-to-Left) once Override Switch is installed ?
Answer: Yes & No. Hitch Pin can be inserted from either direction (left-to-right or right-to-left) thru the truck’s receiver, as long as your hitch pin has the correct useable length as defined herein and it is a straight locking pin type. Your hitch pin must be the correct length as detailed above in these installation instructions. Also, if you are using a standard hitch pin with a hooked end (locking or with a cotter key), then we recommend that you always insert the hitch pin in from Left-to-Right to make sure that the Override Switch clearly can detect that the hitch is installed. Therefore, all straight hitch pins (locking or standard) without a hooked end can be installed either from Right-to-Left or Left-to-Right but any hitch pin with a Hooked end must be installed from Left-to-Right with a hooked end on the opposite side of the truck’s receiver from the Override Switch. Bottom line, for guaranteed accuracy of use, we recommend that you insert your hitch pin into the truck’s receiver from Left-to-Right.
The key is having the correct useable length hitch pin. If you ever run into a problem, just purchase a hitch pin that has a minimum 4.625” useable length . However, ALWAYS use a hitch pin that is 5/8” in Diameter.
What is the button on the Automatic Override Switch for?
The button makes contact with your hitch pin and is then able to detect whether you have a hitch or other apparatus in your truck's receiver or not. When you insert the hitch pin (locking pin or standard hook-shaped pin with cotter key) into your receiver, the hitch pin will make contact with the outside edge of the Override Switch as it slides into place. Once this contact is made the switch detects that there is a hitch or other object apparatus installed in the truck’s receiver and thereby cuts the power off to the inner tailgate portion of the MultiPro™ or Multi-Flex™ Tailgate in order to automatically protect your tailgate from damage. Once the apparatus or hitch and hitch pin are removed, the power is resumed to the inner tailgate portion of the MultiPro™ or Multi-Flex™ Tailgate as it was before installing the hitch in the receiver of the truck.
Manual Override Switch: When button is pushed to activate it does it stay activated until pressed again?
Yes. Push the button to turn the power off. It will stay off until you push it again to turn it back on. The idea is when you kneel down to put your hitch or other apparatus in the truck’s receiver, you are already down there, so press the switch button to turn the power off to the truck’s inner tailgate. Leave it off until you kneel back down to take the hitch or apparatus out of the truck’s receiver and then while there, just push the button to turn the power back on to the inner tailgate.
B&W Tow-n-Stow Hitch : Is the B&W Tow-N-Stow Hitch a real Fix to this MultiPro Tailgate issue ?
Answer is NO. This B&W Tow-N-Stow Hitch is a nice, well-made hitch, BUT it DOES NOT FIX this problem, it only MASKS it. Meaning that the only thing this B&W Tow-N-Stow Hitch does is allows you to leave the hitch in the receiver of the truck BUT in order to do that and for the MultiPro™ or Multi-Flex™ Tailgate not to hit the hitch when tailgate is lowered is for operator to completely MOVE the hitch ball assembly of the hitch, down and under the truck. In order to do that you have to remove, not one, but TWO hitch pins, then slide the entire hitch assembly down and back under the truck, then re-install these TWO hitch pins back into the hitch. Then, and only then, will the MultiPro™ or Multi-Flex™ Tailgate no longer hit the hitch if it is lowered. This does NOT solve the problem as you still have to remember that you have this hitch in your truck’s receiver and if you do, then it still requires action from you to get this B&W hitch out of the way each time, no different than if you had a regular hitch. As a matter of fact, a regular hitch is much easier, lighter, and simpler to move than this B&W Tow-n-Stow Hitch. Bottomline, the B&W Tow-N-Stow hitch is a nice, well made hitch but it is expensive (at over $300) and it does NOT fix this problem. “It’s a nice hitch but you STILL need our Switch!!!“ *** SEE PICTURE IN THE FAQS FOR ACTUAL DAMAGE CAUSED BY THE B&W HITCH ***
The only exception to the above description is IF you have a lifted 2500 or 3500 series truck with the MultiPro™ or Multi-Flex™ Tailgate and a 2.5” receiver size, then, if you leave this B&W hitch ball assembly in the in-use position and in the lowest drop setting it will not hit the hitch ball in receiver BUT if you have a 1500 series truck with 2” receiver size then the B&W hitch will hit the tailgate unless the ball assembly is moved under truck as described above. Therefore, We recommend that IF you have this B&W Hitch that you also install our Override Switch on your truck so that our Override Switch will automatically protect your tailgate and you can enjoy this B&W hitch as well without you having to do anything.
Would a pinless locking style ball mount engage the switch properly?
No, it would not engage our Override Switch to detect whether a hitch was in the receiver or not. The internal pin on this type of hitch does not extend outside of the pin receiver hole far enough to engage the detection ability of our Override Switch. Also, this hitch will not work on the MultiPro™ Tailgate for GMC or Multi-Flex™ Tailgate for Chevrolet as it will hit and do more damage to this tailgate than a standard hitch & ball would. It is advised not to use this style hitch at all on trucks with the MultiPro™ Tailgate for GMC or Multi-Flex™ Tailgate for Chevrolet.
Will the Adhesive Bonding Pad that mounts Override Switch to truck’s receiver, hold up under extreme temperatures, climates, weather, and adverse road conditions?
YES, absolutely! We have been selling our products since 2019 all over the US and Canada and have had zero issues with the adhesive bonding pad holding up, providing it has adhered properly during installation. We use a strong industrial strength 3M product that is designed to adhere to steel or aluminum surfaces and holds very well in climates with temperatures as low as -50 degrees to as high as +250 degrees. Furthermore, for those customers that just may want additional security for peace of mind purposes, if you have the capability, after you install the switch as directed you can always place a very small tack weld in one spot to further adhere the Override Switch to the receiver.
What if the Override Switch fails and causes a dent in my tailgate?
This is not likely to ever occur as we have designed our switch so that, if properly installed, and in the event the Override Switch fails to work it will actually default to cutting the power off to the midgate section of the tailgate so it cannot be lowered to allow damage to tailgate. The only way a perceived failure like this could occur is if the user were not using the properly sized hitch pin OR are using a hooked hitch pin and have inserted the pin into the truck’s receiver from Right-to-Left, rather than from Left-to-Right as directed, causing the hitch pin to lose connection with our Override Switch. See our full instructions explaining the correct hitch pins to use.
Once Installed is there any maintenance that needs to be done to the Override Switch?
Once you install your Override Switch on your truck, there is really nothing needed in terms of maintenance EXCEPT (1): we would recommend you clean it off when your truck gets really muddy or dirty AND (2): it would be a good idea to squirt a little WD-40 on the Stainless Steel dome-shaped switch head from time to time just to keep it lubricated and looking shiny and new.
