Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - 2012 Terrain by GMC

Quickly and easily install a 4-way trailer connector on your GMC Terrain with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.

Features:

  • Provides a 4-way flat trailer connector at the back of your GMC Terrain to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind tail lights
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Made in the USA
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your GMC Terrain's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.


Once installation is complete, the 4-way connector will be stowed beneath your GMC Terrain, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Video Transcript for Trailer Wiring Harness Installation - 2012 Chevrolet Equinox

All right today on this 2012 Chevrolet Equinox we're going to install part number 56094 from Curt. This is a Curt T connector vehicle wiring harness with a four pole inaudible 00:00:10. All right, first thing we need to do is go ahead and get access to the wiring harness. We'll go ahead and lift up the tailgate and then we need to remove the tail lights. We'll remove the covers to get access to the fasteners. We'll do this on both sides of the car. We're going to pop them out with a screwdriver and then we'll remove the bolt inside.

We'll use a 10 millimeter socket to remove it. All right, we'll go ahead and work the tail light loose, pull straight back and rock it from side-to-side and then we can go ahead and disconnect it from the tail light. Push down on the tab right here on the wire connector, sometimes it helps pushing first then push the tab and pull it apart. Okay, we're done with our drivers side we'll go ahead and repeat the same thing on the passengers side. Okay, now our vehicles ready to install our wire harness. We'll go ahead and take our four pole and drop it down between the body work and the bumper cover.

We'll take our T connector yellow wire and plug it into the drivers side wiring harness until it snaps. We'll sit that aside for now. We'll go ahead and take our T connector with the green wire and go ahead and route that down and around. All right, now we'll go ahead and pull out our wire harness. All right, we'll go ahead and route this four pole over temporarily to our hitch. Now we'll take our T connector with the green wire and go all the way across and eventually up to the tail light on the other side.

All right, now we can go ahead and pull our T connector with the green wire from the bottom up to the top. We're using an old piece of airline tubing to help pull it up, but this also could be an old coat hanger or any other stiff piece of wire to help pull it up. Okay, then we'll go ahead and take our T connector and plug into the wire harness on the vehicle. At this point we'll go ahead and take our white wire with the ring terminal and we'll go ahead and attach I t to the sheet metal here. All right, at this point we'll go ahead and take up some of our access wire. We'll go ahead and leave some out and then just tie it off to help hold out.

Eventually we'll go ahead and put a bracket to hold our four pole in place. Now we'll go ahead and zip tie our wires to the hitch and also make sure we keep it away from the exhaust as they go toward the tail lights. All right, now we're going to use some zip ties to help hold our wiring to the hitch. These are longer zip ties that didn't come with the wire harness. Always a good idea to get some extra zip ties anyway. To help hold our wire up we'll go ahead and use a loom clamp, part number A0250. We'll attach it to the sheet metal going down here. To give you some extra working room we just push down the exhaust a little bit using a wooden block. Okay, we'll pull up our access wire and we'll zip tie it. Okay, we're done with our drivers side. We'll basically repeat the same process over on our passenger side. All right, once we have our wires routed the way we want them we'll go ahead and just cut off tails on our zip ties and our passenger side it was just long enough. Our tail light will actually support the wire and take up the slack. I'll take a look at our access wire we have here. We can go ahead and bundle up some extra and we'll zip tie it to itself in case we need to add a length to it. Okay and at this point we can go ahead and reinstall our tail lights. The T connector will plug into the socket on the tail light and we can go ahead reinstall it. Okay, with that everything is reinstalled. Now we'll go ahead and try out our wiring harness to make sure it works before we try it on a trailer. All right, now to test the wire harness we'll take the ground on our tester attach it to the white wire and then check our brown wire for a running light circuit. Yellow will be our left turn, green will be our right turn, and then our brake signal will be a constant signal on the green and yellow wires. All right everything works. We'll go ahead and put on our cap for our four pole. Now if you use to help hold everything in place, but wait there's more. Instead of doing this we'll use a bracket to help hold it in place. We use part number, 18144 from Tow Ready. We'll take the bracket, put the four pole through and friction will hold it in place. Grab it with a pair of pliers and help pull I through. All right now to help hold our bracket in place we'll use part number 18140 also from Tow Ready. This bracket will get clamped to the hitch. This will be our clamp, run it through the bracket and over the hitch. Make sure you don't smash any of the wires. Run the clamp back through itself. Once we have the clamp loosely installed we'll go ahead and tilt it down, it makes it easier to attach our two brackets. We'll put it together using the hardware that comes with both pieces. We'll go ahead and take our bracket going to the hitch, push up the way we want it and then tighten up our clamp. Then we'll take our tail for our clamp and we'll just bend it up and out of the way and fold it over itself that way we won't have a sharp edge hanging down. There you have it for part number 56094 from Curt on our 2012 Chevrolet Equinox. .

This wiring harness is very easy to install. I had a bit of trouble getting the tail lights out of our 2012 equinox but with a a second set of hand they slipped out without doing any damage. I used extra zip ties and wire loom to help protect the wire. Be sure to keep it away from the exhaust if you have a V6 with duel exhaust tips. I modified a Curt rubber tube cover to secure the harness to the receiver. I made sure to leave extra wire in behind the hitch so that I can pull it through when I need it. 63065

Of the two Wire Harness's available for the Terrain and Equinox from etrailer, the Curt #56094 is absolutely the one to purchase. With this one, you do not have to run a wire all the way from the back of the vehicle to the front and make a Battery connection, like you have to with the other harness available. Excellent quality and installs easily, without the hassle of running a wire to the Battery. Curt trailer products are second to none.25947

Curt T-Connector wire harness. Easily installed on my 2011 Chevy Equinox. Fit like a factory wire harness complete with waterproof connections. The video shows it all. Only thing I added was some black plastic wire loom to complete the illusion of a factory installation. Thanks for a great product. 14443

I received the towing hardware a few days earlier than I thought I might. I read the instructions a couple of times and had the hardware installed, by myself, within 30 minutes. It took me about the same amount of time to install the wiring harness. There were no surprises and I could not be happier.124906

This was a small challenge. I did it myself and have very few tools. additionally at 75 with knee replacements I cannot get up and down very well, nor can I sit on my knees. (Butt only) Other than the minor adjustments normal for metal sizing once treated all went very well. Zero issues...."IF" you don't count some pain. Very well constructed product.105845

The install went without a hitch, (No pun intended). I liked the product for the 2013 Equinox and the fit was perfect. I would recommend you finish protecting the wire with either plastic spiral wrap or the plastic split wrap to protect the wire from wearing against any sharp edges under the vehicle. It is readily available from your big box hardware store.86044

The wiring is very easy to install and worked perfectly for me the first time I used it. The video walkthrough was spot on, it only takes about 15-20 minutes to install and doesn't require you to run a wire up to your batterey at the front end of the vehicle. Besides installing the ground wire with the self-tapping screw, the rest of the instalation only involves plugging in the 4-way adapters to your existing taillight wiring. The product arrived as decribed and I would absolutely reccomend this product.82234

Both the hitch and the wiring harness were a breeze to install. Watched both install video's before attempting to the job and it made it very easy. Hitch looks great and wiring the harness with the T connectors made the electrical hookup a snap. Thanks for all the info (videos) that made this job simple.68428

I need a wiring product for my 2012 terrain the the local didn't stock the right one. To order One would take three to four days and I needed it quicker then that (poor planning on my part) and they ask over double the price that I got from you. You also gave an option on shipping te and cost. I was very pleased with your service You can always purchase like products but when it comes to service your company stands out. I will be purchasing a flat tow bar in the near future and be ordering it from you. Keep up the good excellent service. Thanks Jim52012

To EASY to install. I purchased this product for my 2012 GMC Terrain AWD 4 Cylinder. Just like the instructions I removed the screws for the tail lights, popped them off (you need to pull straight back and a little hard because the tail lights have straight clips behind them, they won't break, the clips go straight into the vehicle body) and clipped in the harness as directed. Too EASY. When putting the tail lights back on be cautious not to smash the rubber lining which runs above the tail lights on the vehicle itself. GREAT PRODUCT!!!!!!!46024

Quick delivery. Clear instructions, good quality (good powder coating job). Easy to install (you don't need to move the tail pipe). Make sure weld nuts on the vehicle are cleaned out well before starting. A little grease to the bolts also makes them thread easier. Used with a trailer light kit. As always, very satisfied w/ etrailer.com products.34262

Simple installation...I mean SIMPLE!!! The only suggestion that I could make would be to have some sort of mounting bracked for the trailer connector instead of letting it dangle loose. I know the instructions show the rubber cap keeping it in place, but that is still a little flimsy. Otherwise, very easy and took 15 mins to install.32587

Couldn't ask for a more elegant and efficient install. Took all of a half an hour, and it was that long only because of my arthritis. Those cable ties become a bear when you fingers don't work right. And the dealer had the audicity to want a hundred dollars to do the same thing.20013

I recieved the harness pronto, but after removing the two screws holding the tailight assembly in on my 2013 GMC Terrain, the assembly dont want to come out, Im afraid to us much pressure on plastic. Any suggestions?

Check out the link to the video. At about the 30 second mark, our installer removes the driver side tail light. After that, you can see the two plastic pins, and their corresponding holes, close to the outside edge of the body. Wiggle slightly as you pull straight back, and you should be fine.

  • Does a T-Connector Trailer Harness Need to be Plugged into Vehicle ECU
  • Curt T-Connector harness part # 56094 does not need to be plugged into the computer of the vehicle. T-Connector style harnesses plug into the tail light wiring connectors with an additional wire that will need to be grounded to the vehicle body or chassis. Sometimes there is another wire that will need to be run to the battery.

  • Does the T-Connector Wiring Harness Violate the Warranty on 2010 Chevy Equinox
  • The T-Connector Wiring Harness for the 2010 Chevy Equinox, part # 56094, is very easy to install. You will simply plug it into the factory connectors behind your tail lights and you will be ready to tow. Installing a wiring harness will not interfere with your warranty. I would recommend two things. If you will be towing frequently, I suggest a mounting bracket like the 4 and 5-flat Trailer Connector Mounting Box, part # 18145, to keep your plug from dragging the ground. I also recommend some Di

  • Comparing Trailer Wiring Harnesses # 56094 and # 118494 for a 2011 Chevy Equinox
  • The Curt T-Connector Vehicle Wiring Harness with 4 Pole Trailer Connector, # 56094, will fit your 2011 Chevy Equinox and will work to operate the trailer stop, turn, and tail lights. But, it does not have a circuit protected or powered converter to protect your vehicle wiring. If given the option, I will always recommend the circuit protected powered converter, # 118494, because it is designed to protect your vehicles sensitive wiring. What it does is virtually eliminate the extra power draw

  • Trailer Wiring Recommendation for a 2010 Chevrolet Equinox, Circuit Protected vs Unprotected
  • We stock both the Tow Ready Custom Fit Vehicle Wiring, # 118494, and the Curt Custom Fit Vehicle Wiring, # 56094, because we have customers that request both styles. Many times customers do not want to run the extra wire to the vehicle battery, so they order the # 56094 harness. The Battery connection is the biggest advantage of the # 118494 harness for protecting the vehicle circuitry. I would use the circuit protected model, # 118494, because there is always a possibility of a short circuit

  • Does the Computer have to be Reset to Install a Curt Trailer Wiring Harness on a 2012 GMC Terrain
  • I went over the installation instructions and you will not have to have the computer reset when you install the Curt wiring harness, # 56094, on your 2012 GMC Terrain. If you are apprehensive about it, you could always disconnect the negative battery cable prior to installing the harness. You will use any programmed information, like stereo presets, but that is easy enough to reset.

  • Trailer Lights do not Work with the Curt T-Connector Harness # 56094 on a 2013 Chevrolet Equinox
  • According to Curt, the T-Connector Trailer Wiring Harness, # 56094, that you installed is compatible with your 2013 Chevrolet Equinox. It sounds like there may be an issue with the wiring harness itself since your trailer lights work with another vehicle. The first step I recommend taking is to inspect the connections for the wiring harness and make sure it is grounded properly. If you see any pinched, frayed or damaged wires, the harness could be shorting out, which would explain why your ve
