How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2020 Chevrolet Traverse

Ryan: Hey everybody, Ryan here at etrailer. Today on our 2020 Chevrolet Traverse, we're going to be taking a look at and showing you how to install the Tekonsha T1 Vehicle Wiring Harness with the four-pole flat trailer connector. So in my opinion, this is probably the best choice to go with as far as the four-pole flat trailer connectors go for your Traverse. It's really well built. It's going to work really good. Everything down from the wiring to the actual cap that protects the terminals is just really solid.So the wiring is going to provide your trailer with the necessary lighting functions to not only be safe, but legal as well.

It's going to give you those running lights, your brake lights and your left and right turn signal. The wire is going to put out plenty of power to illuminate any type of bulb, whether you have a trailer that's a little bit older with the traditional-style incandescent lights, or even a newer style trailer that might have LEDs. This will have no problem getting them to work.What's really nice about this setup too, is that everything's going to fit behind this panel. That way, whenever you need to use it, it's going to be easily accessible, but whenever you're not using it, you can take that panel, put it back in place and everything will be nice and hidden.So what I really like about this is the fact that it's already going to utilize the factory wiring that's already there. Really puts my mind at ease knowing I'm not going to have to cut or hack into anything.

Because of that, the installation is going to be really straight forward too. It shouldn't take you a whole lot of time at all. Speaking of which, let's go ahead and hook up the wiring together now.To begin your install, you're first going to need to locate that factory plug, which is on the driver's side. Now we're doing a hitch at the same time and so we're going to do the wiring while the fascia is off, because it's so much easier to work with and see. However, I want to point out that the fascia does not have to be removed.

If your bumper is all put together already, you can still reach your hand from the bottom up and get this done. And once we do actually have everything back together, I'll give you a shot of where you can see and how you would do that.So if we grab our plug, you can actually pull it back a little bit and out and that'll free it from the body of the vehicle, make it a little easier to work with. And it's going to be a cap here or this dummy plug that we need to take off. WE'll have a red tab, you pull that out and then push down on the center and separate the two. We'll set this dummy plug to the side because we won't be reusing it.

Then we can grab our trailer wiring. What I like to do is take some dielectric grease and just put a layer over the terminals to help prevent any corrosion. You can find this dielectric grease here at etrailer if you need some. And it's just as simple as plugging it in. With this plugged in now, we can reattach it to the body of our Traverse. It just slides back on this clip. With that secured, we can take our four-pole wiring and run this over to our mounting location on our hitch.So I'm going to go ahead and get that done now, and then I'll show you what it looks like once I have it there. So here's what our wiring looks like once I ran it over to our mounting location and I just used a couple zip ties to help keep all that wiring secure. I just followed it right there along the hitch and down here to our bracket. We are going to have a ground wire that we need to attach. It's going to be this one here with this pre-attached ring terminal. So what I'm going to do is just go behind our hitch and I'm just going to attach it right here to the body of our vehicle. You don't have to attach it here. You just want to make sure that it is a solid piece of metal that'll provide us with that good ground. I'm going to do that using the included self-tapping screw.Now if you did take your bumper off, before we get everything back together, it's a good idea to test our wiring out. We're using a tester you can find here at etrailer or you can always just hook it up to your trailer. So go ahead and try our left turn, our right turn, our brakes. And finally our running lights. Now that we've verified everything is working properly, what I'm going to do is go ahead and put our bumper back on, and then I can show you how to get this installed and where the plug is if your bumper was not removed.So now with the bumper on, as you saw earlier, our connector is right here in this area. So what you can do is this opening here behind our bumper and in front of our muffler, you can reach your hand up there about halfway and you can actually pretty easily feel that connector. You'll see a bundle of wires running right over to here. And this is exactly where this connector is. And so if you do have the bumper on, what you can do, how we actually remove that plug from the body of our vehicle, we do that same thing, and it'll drop down and give you quite a bit more room to work with.And that'll finish up our look at and our installation of the Tekonsha T1 Vehicle Wiring Harness on our 2020 Chevrolet Traverse.
