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:
Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the center of the rear bumper.
Once installation is complete, the 4-way connector will be stowed beneath your vehicle, 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.

This wiring harness was plug and play, very easy to install.
Well it was easy to plug in, but everyone said if you have the plug behind the bumper it will work.... Yes and NO. Guess my vehicle is the one that was not wired for running lights through that plug. 4 way, brake turn all work but no running lights.. There are no relays in the fuse box for those, and since I lease I'm NOT cutting and splicing into the vehicle.. 23 Chevy Equinox. Looking into Battery powered lights as an emergency if I get stuck in the dark sometime.. Maybe wire 2 taillights with a lawn tractor battery????
This was an exact fit for 2021 GMC Terrain Denali...even though the dealership said the vehicle was not equipped with the pre-wired trailer light inline plug...It was and this worked
Watched a video and installed the hitch and lights with no problems.
My 2020 GMC Terrain Denali without the trailering package already had the wiring under the bumper so this kit took less than 15 minutes to install.
Great product and super easy to install following their video tutorial. etrailer is the only place to buy your towing accessories.
Had to return harness no problem took back for refund you need towing parts they have what you need
This was by far the easiest thing I’ve done to my car just plug it in and done. Space was a little tight but it wasn’t the harness. Well worth the money I would have paid triple to keep from having the headache of running wires.
Plug and play.
Plug-n-play.
Worked as expected.
Will continue to order parts as needed from your company.
Best customer service ever!!!
Simple, clean, snap-in installation. Solid construction with heavy duty components. Easiest car wiring I've ever done.
The Curt T-connector vehicle wiring harness with 4-pole flat trailer connector was a perfect match for my 2022 GMC Terrain. The harness plugged into the trailer wiring harness that was already present located behind the center of rear bumper. Thanks E-Trailer.
Super easy hook up and does exactly what it's supposed to
Fast Shipping looks great
With problems with stocking hitches ANNAE kept me well informed finally found a hitch and promptly had it delivered more than satisfied!! So much so that I ordered two more parts for the hitch!!
Worked perfectly!
as expected
worked great
this is really plug and play, it doesn't get any simpler.
Works perfect and installation was a br eeze
My dealer told me that GM would not sell me one for my Equinox because it was not designed for towing so I was pleasantly surprised at how easy the install was. Fits like a glove when following provided instructions.
As described
Not much to say.If your equinox has the factory plug you just plug this in,secure everything and your good to go.

The wiring harness hooked up very easily, and is holding up very well. I’ve had no problems with it at all.
