F.A.Q & Contact Information
Will my warranty be affected by installing this switch?
Since our design doesn’t affect anything more than regulating power to a portion of the tailgate and it does not permanently modify the vehicle in any way and the switch can be easily removed from the truck, then, it should not affect your warranty or any applicable lease
agreements. We have had several discussions with dealerships who confirmed this. We can confirm we have dealerships ordering our product for their customers. Having said that, when purchasing any aftermarket product for a vehicle, the GMC Warranty can be affected
by the installation of any aftermarket product. GMC created this problem issue and Tailgatefix.com has provided a high quality solution to remedy it for all of it’s owners of this GMC truck. We would be very surprised if GMC would ever object to this being installed on these trucks OR would allow the installation of it to effect your Warranty in any way. They have to be delighted that Tailgatefix.com has provided The Fix to this problem.
My adhesive tape seems not be sticking to the receiver strong enough to keep all in proper placement ?
The adhesive Tape that we use to adhere the switch to the Truck’s receiver is strong Industrial strength that is designed to adhere to a steel surface and hold very well in climates from -6 degrees up to as high as 195 degrees. Main thing is that when the Switch is 1st installed on the truck’s receiver, make sure that do the following : (1) thoroughly clean your truck’s receiver with an alcohol wipe and let dry; (2) IF you are in a colder climate area, use a heat gun or hair dryer to heat up the truck’s receiver surface to approx. 60 degrees; (3) make
sure your hands are clean of any dirt or grease; and (4) make sure that once you remove the adhesive tape’s protective strip backing that nothing comes in contact with the sticky portion of the Tape until it is adhered to the truck’s receiver. Once it is properly adhered to the truck’s receiver, it has a very strong hold and will hold up nicely in basically all type of weather conditions and temperatures.
My Multi-Pro mid-gate will not open : “All I hear is a click sound when I touch button.”
Some GMC Truck owners with the MultiPro Tailgate may periodically experience an issue with their mid-gate not releasing when the main tailgate is lowered. (ie. when you push the mid-gate button to open it the truck’s back lights blink AND you hear a “click” sound but the mid-gate will not open to drop down.) This is an existing issue that GMC 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 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 mid-gate 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 :
1. Remove the hitch and hitch pin from your truck’s receiver. Raise main tailgate to its upright closed position. Then, Press and
Release BOTH buttons on tailgate at the same time. By doing this you should see both the main tailgate and the mid-gate open and lower down at the same time.
2. 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 mid-
gate at the same time that you press and release the button to lower the mid-gate. It should now lower as normal and not stay
closed and just produce the“click” sound.
3. 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 mid-gate. The mid-gate 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 mid-gate and
just results in the truck’s tail lights flashing and you hearing a “Click” sound which indicates that power is getting to the mid-gate 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 mid-gate the mid-gate 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.

Will the switch for a 2500 series truck also work with a 3500 series truck ?
Yes, our 2500-Auto Override Switch will work on the 3500 Series GMC truck as long as the receiver on your 3500 series GMC truck is the same 2.5" wide receiver size as is on the 2500 Series truck. If you have a 3” wide receiver, (measure the inside width of the receiver on the truck to find out), then our 2500-Auto Switch would not work. If you do have a 3” wide receiver, then, order our 3500-Auto Switch with 3” receiver and if you have a 3500 Series truck with a 2.5” inch receiver then order our 2500-Auto Switch. You would also need to use a 5/8” diameter x 4.5” min long hitch pin. However, Our Manual model version of our Override Switch will work on ANY SIZE truck receiver.
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 in your truck's receiver or not. When you insert the hitch pin (locking pin or standard hook shaped pin with cotter key pin lock) 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 mid-gate portion of the MultiPro Tailgate in
order to automatically protect your tailgate from damage. Once the hitch and hitch pin are removed, the power is resumed to the mid-gate portion of the MultiPro Tailgate as it was before installing the hitch in the receiver of the truck.
Can the pin be reversed and be inserted from Left-to-Right instead of Right-to-Left?
Yes, as long as the correct length of the standard or locking pin is used according to the installation instructions, you can insert the pin left-to-right and it will work just fine. The key is having the correct length of the pin. If you ever run into a problem, just purchase a hitch pin that is ½” (inch) longer than the one you are currently using that is giving you a problem. However, ALWAYS use a hitch pin of whatever length that is 5/8” in diameter.
B&W Tow-n-Stow Hitch : Is the B&W Tow-N-Stow Hitch a real Fix to this MultiPro Tailgate issue ?
The answer is NO. This B&W Tow-N-Stow Hitch 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
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 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 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. “ Its’ a nice Hitch But you Still need our Switch !!! “ 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.
My switch doesn’t work as the pin doesn’t touch the switch to activate it.
Your GMC Sierra 1500 truck has a 2” wide hitch receiver. So, if you use a locking hitch pin, then you will need to use one that is at least 3.5 inches long. IF you use a standard or locking hooked hitch pin, you will need to use one at least 4 inches long and we recommend that you insert the pin into the Truck’s hitch Receiver from left-to-right putting hook side of pin on the left side of receiver opposite from the Override Switch. If you do insert hooked pin into receiver from right-to-left with hook on same side as the Override Switch, you must make sure to keep the hook portion pointing downward or towards Switch otherwise if pin is too long it may shift in receiver and could cause switch to seem not to engage properly.
I installed the Override Switch, but now the Mid-gate 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 connections that you made under the truck. Check to make sure that the blue/white wire connectors that you placed the Override Switch and purple truck wire into have been COMPLETELY Crimped down to make a clear connection to both the wires in each connector. Sometimes, if you do not crimp the blue top on the connectors all the way down with Channel Lock or Slip Lock Pliers to where you feel it click, it will not cut through the wire insulation completely to make a
clear connection. (*) See photo below for an example of one where only one of the blue/white connectors were crimped down properly. You will see the break in the insulation on the “Black” wire but there is no corresponding break in the insulation on the “Red” wire.
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 14 gauge steel. The interior components are sealed with liquid rubber to keep all moisture away from connections and working parts. As an added point of protection, we even apply a final coating of clear silicone to the top of the switch housing where wiring exits as well as we mount a rubber seal washer around wire and secure it to the top of the switch housing. The wiring has a solid exterior PVC jacket with two PVC insulated interior conductors. The Switch is connected to the truck wiring with full moisture-proof silicone-filled enclosed connectors all together designed to help keep moisture and temperature from
What size Hitch Pin should I use with my Splitgate Override Switch ?
All Automatic models of our Splitgate Override Switch are designed for a 5/8” diameter hitch pin. You cannot use a smaller ½” diameter hitch pin. Required Hitch Pin : 1500-Automatic Override Switch requires a minimum 3.5” inch long Hitch Pin; a 2500-Automatic Override Switch requires a minimum 4” inch long Hitch Pin, and a 3500-Automatic Override Switch requires a minimum 4.5” inch long Hitch Pin.
Will my Override Switch work if I insert my Hitch Pin into the truck’s receiver (from either direction) once Override Switch is installed ?
Yes, Hitch Pin can be inserted from either direction (right-to-left or left-to-right) thru the truck’s receiver. However, your hitch pin must be the correct length as detailed in the installation instructions. Also, if you are using a standard hitch pin (hooked pin with cotter key) and our Override Switch in mounted on the right side of the truck’s receiver, then we recommend that you insert the hitch pin in from Left-to-Right just to make sure that the Override Switch clearly can detect that the hitch is installed. However, IF you do install a Standard Pin in from Right-to-Left it will still work just fine as long as you slide the pin into receiver with the hook in the pin facing downward or back towards the Override Switch.
I’ve purchased two different pins but the female piece is never small enough to sit flush with the hitch because the Splitgate Override Switch prevents the female portion of the hitch pin from sitting flush.
For our Automatic model Override Switches, once installed, IF you use a standard or locking hooked hitch pin, we recommend that you insert the pin into the Truck’s hitch Receiver from left-to-right putting hook side of pin on the left side of receiver opposite from the Override Switch. If you do insert hooked pin into receiver from right-to-left with hook on same side as the Override Switch, you must make sure to use one that has at least 4” of useable length and keep the hook portion pointing downward or towards Switch otherwise if
pin is too long it may shift in receiver and could cause switch to seem to not engage properly. If you use a straight locking or standard hitch pin, you may slide your hitch pin into your truck's receiver from either direction (Right-to-Left or Left-to-Right). If you have a 1500 Series GMC truck, make sure that you are using at least a 3.5" long straight locking hitch pin or 4” long standard hook shaped pin with lock or cotter key that has a Standard pin diameter of 5/8". All pins for all truck sizes must be 5/8” diameter.
Manual Override Switch: When button is pushed to activate it does it stay activated until pressed again?
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 in the truck’s receiver, you are already down there, so press the switch button to turn power off to the mid-gate. Leave it off until you kneel back down to take the hitch out of the truck’s receiver and then push the button to turn power to mid-gate back on again.
Would a pinless locking style ball mount engage the switch properly?
No, it would not engage our Switch to detect whether a hitch was in the receiver or not. The internal pin on this hitch does not extend outside of the receiver hole far enough to engage the detection ability of our Override Switch. Also, this hitch will not work on the GMC MultiPro Tailgate 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.
