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.

Video Transcript for T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector-TK74VR Spec Review

Michael Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at this T1 vehicle wiring harness. This is going to provide a four-pole, flat trailer connector at the back of your vehicle. So, that you can get your trailer hooked up and your light signals are going to function on your trailer, just like they are on your vehicle. So, this is going to be a super simple installation.

It is a custom fit for your 2021 and newer Buick Envision. This is one of the most simple setups there is for a trailer wiring harness, like this. I've seen a lot of these, and this is probably the easiest one I've ever seen. Basically, all you have to do is locate the plug that's on your vehicle. It's on the underside of your vehicle behind the rear bumper, on the driver's side of center.

It's got a cap on it that's going to match this plug side here. So you just have to take that cap off, plug this in, and then basically you're ready to go. You'll wrap this up to where it's going to be accessible to plug in to your trailer's wiring. You're not going to have to worry about splicing your vehicles wires, voiding your vehicle to warranty. Anything like that.

It's super simple plug and play option. It's going to then provide that output for your trailer. Now this is the four pole, or four-way flat trailer connector, but there are adapters that will work with this So if your trailer has a five pole, a six pole, or a seven pole, we've got adapters [email protected], that will convert this four-way to all of those other options so that it will still work for your trailer. This is going to provide 4.2 amps per circuit for your stop and turn lights and 7.5 amps per circuit for your tail lights. So really nice option here.

Like I said, the instructions to walk you through step-by-step, just those two or three steps. The one thing I will note when you're routing this wire, you do want to make sure that you're staying away from anything that's going to be hot or moving, or that could potentially damage that wire. But that's basically all there is to it. So with your vehicle, it is going to be extremely simple to get this installed. So just about anybody can do it. I just have to get up underneath that rear bumper, find that plug and plug it in. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

There was no installation video which after receiving the wiring harness I know why. It was a challenging spot to get to. The instructions show removing the rear fascia… I recommend removing the one bolt holding the exhaust heat shield on the driver’s side and reaching up to grab the harness. You will have to do this all by feel because you can’t see while doing it. It only took me about 10 minutes to do including figuring out when the plug was, but an install video would be nice for this.

For 2023 Buick Envision. Fast delivery. Well made, installation went as described. I would have given it 5 stars, but the pictures in the instructions were too small to be of much use. Larger pictures would have made the install easier. Diagrams or pictures of which way to pull on panels to release snaps would have helped. Rather than unplug the connections, I just hung the rear bumper cover from a couple ratchet straps above the bumper to swap in the hitch. The install took like 5 hours, as I was unfamiliar. Doing it now that I've done one would be 1/2 that time.
