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

Ryan: Hey everybody, Ryan here at Today on our 2020 Chevrolet Traverse, we're going to be taking a look at and showing how to install the Tekonsha T-One vehicle wiring harness with a seven-way connector. What I really like about this seven-way is that it's going to provide our trailer with multiple different functions very easily. That's because this just plugs right in.Now, what it's going to provide our trailer is the basic functions like your stop and turn, your taillights, and your reverse lights. But it's also going to do a couple more things. It's going to have a 12-volt power output.

That'll help power anything that you might have on your trailer. It's also going to put out an electric brake signal if your trailer has electric brakes and you plan on using a brake controller.The plug itself is going to be nice. That's for a couple of different reasons. The cap is going to be spring-loaded. It's also going to have a seal on the backside of it.

That way, when we're not using it, it's going to stay closed nice and night. You don't have to worry about any debris or anything like that getting inside, potentially damaging our terminals.If we do open it up, and once we plug our connector in, there's going to be a piece that comes down right here. That's going to prevent that connector from accidentally getting pulled out. So overall, a really quick and easy way to be able to connect your trailer. That way you're able to pull it down the road safely and legally.

Since this does just plug right in, the installation is going to be really straightforward and shouldn't take you a whole lot of time at all. Speaking of which, let's go ahead and do that together now.To begin our installation, we're first going to need to locate our factory plug. That's going to be located on the driver side right here in this area just behind our bumper. If we look up behind our bumper, we're going to be able to see some wiring with a plug on it just above our exhaust hanger. This is the plug that we're looking for.

Now what you can do to make it a little easier to work on is reach your hand up there and push towards the center of our vehicle. That'll release that plug. That way, we're able to drop it down and give us a lot more room to work.Now once we have this pulled down, there is going to be a little cover on the plug that we'll take off. To do that, we'll take this red tab and push down on it. Then you're able to push down on the center of that tab there and pull the two apart. Now before we plug our connector in, it is a good idea to loosely route it. In our cases, we're going to mount our seven-way plug somewhere in this area on the hitch. What I've done is just ran our wiring up and relatively close to the area where we are going to plug it in. Now the reason I do this first is because it's a lot easier to run this end through some of the openings because it's a little bit smaller than our seven-way end.With that being said, what I like to do before we actually plug the connectors together is take some dielectric grease and just put a layer over the terminals here. That'll just help keep it protected from any corrosion or anything like that. If you need some dielectric grease, you can find some here at Once you we have it coated, simply line the two connectors up and get them plugged in.Now we can go ahead and put some dielectric grease on the connector here at this end. Once we have it coated, we can grab our seven-way plug and get it plugged in. Now I want to point out, the kit doesn't come with any brackets. It's just going to come with your seven-way plug. I'm using a couple different types of brackets here. That way we're able to not only mount our plug but secure it to the hitch. If you need some brackets, there's plenty of to choose from here at that being said, these two simply just line up and plug into each other. If I'm connected, now I can come back and secure my bracket to the hitch. With our seven-way all mounted up, I went ahead and used some of my included zip ties to secure our wiring up and out of the way. Just to give you an idea on how I actually routed my wiring, the path that I took was just along this edge here behind our back bumper. Then I actually went up and over our exhaust, then was able to plug into our connector. Now you want to be sure to do your best to avoid any hot or moving parts when you route yours.Now it's always a good idea to test our wiring to make sure it's functioning properly. I'm just using a tester box, but if you don't have one of these, you can always just hook up to your trailer. The first thing we're going to do is make sure we have power back here. If I flip this switch, you'll see the needle on the DC voltage gauge go up, so we know we're good as far as the power goes. Now if we go inside the car, we can they're our left turn, our right turn, our brake lights, our running lights, and our reverse lights. That'll finish up our look at and our installation of the Tekonsha T-One vehicle wiring harness with a seven-way connector on our 2020 Chevrolet Traverse.
