How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2019 Chevrolet Traverse


Rob: Rob here at etrailer.com, and today, we're going to be taking a look at the Tekonsha T-One Vehicle Wiring Harness with a seven blade RV-style connector on our 2019 Chevrolet Traverse. Now, our Tekonsha wiring is going to provide us with all the lights we need to get down the road safely, like our taillights, our turn signals, our brake lights and even our reverse lights, but it's also going to give us a brake output signal in case we have a brake controller in our Traverse, as well as a 12-volt power source to power anything on our trailer. Now, our 7-way connector is going to have a spring loaded door, so we don't have to worry about it coming open and anything getting inside. There is going to be a gasket on the inside of the door as well to keep all that dirt debris, moisture, or anything else from inside the connection points.Now, if we also look on the door, we're going to have this little notch here and that's what's actually going to catch onto your 7-way plug and prevent it from getting pulled out while we're driving down the road. And one of my favorite things about our wiring is how easy it installs. A lot of customers are worried when it comes to wiring about cutting or splicing into their vehicle.

And with good reason, I don't want to do it either, but our Tekonsha wiring is going to have one plug that we simply plug in behind our bumper and then we round our seven pull towards our receiver hitch. The hardest part of it really is going to be accessing the plug because it's going to be above our exhaust on the driver's side, behind the bumper. But we'll go ahead and show you exactly where that plug is and walk you through the rest of the installation now.To begin our installation, we want to come to the back of our Traverse. Now we have a hitch installed and it's behind this panel. So when you remove that panel, we'll have two turn knobs at the very bottom corners.

We'll turn them counter-clockwise and we'll grab our panel and we'll lift the whole thing up and then we can pull out and down and pull the panel away. Now, ideally you want to mount your 7-way really close to where your receiver tube is. Now in our application, we have a bracket already welded onto our hitch, but we need another bracket to mount our 7-way so we're going to be using the POLLAK 7-way Mounting Bracket and it'd be a good idea to pick one of these up because the slotted holes are going to make it really easy to mount your 7-way. We're not going to have to worry about getting a specific one. But I'll take the hardware.

I'm just going to loosely get one started so I don't have to worry about the bracket falling down. Now, we'll put the other screw and nut in on the other side. I'm going to come back with the 10mm socket and since these are lock-in nuts, we should just be able to hold it with our finger and tighten up this nut on the bottom side.Now that our bracket is mounted and ready, we're going to move over to the driver's side, right by our exhaust pipe. Now, right above that, right about this general area, we're going to have our factory tow package plug. It'll be a little bit difficult to see, but if we reach our hand up right past the exhaust hanger here, we'll feel the harness and we'll be able to grab it and pull it down.

It's going to be this plug right here. You're going to have a push pin that's going into the body and we can either grab the plug itself, or we can try to push that push pin out of the body, pull it down with the plug. We'll pull our plug down. It's going to have a cap on it so we're going to pull down on that red tab to unlock it, and then we'll press in on the center pin and separate the connector.Now that we can see a little better, here's a small red tab that's going to be on the cap. We're going to pull it out so it releases it and we'll press down on that black section and pull the cap off. At this point, we want to grab our harness and we're going to be paying attention to the end that has the rectangle plug on it. I'm going to start really close to my bracket and I'm going to go on top of my hitch and we're going to start feeding it towards the driver's side. That way I can meet up with my plug on the other side.You just want to stay away from the exhaust as much as you can and try to stay as high as you can to prevent any kind of damage to our wire. I ran it all the way over to where my other plug is. I'm going to take a little bit of dielectric grease. I'm going to fill this cavity up, and hopefully it'll prevent any kind of moisture or corrosion buildup inside the plug. We don't have to worry about any bad connections. But we'll take our plug now. We're going to plug it into our tow package harness.Once you have it plugged in, we're going to make sure that it's locked in place. It's a good idea to give it a quick tug. And then we can take that push pin fastener that's on the original harness and push it back into the hole so it's nice and secure and far enough away from our exhaust. We'll put some dielectric grease on the 7-way end of our connector as well. Make sure you get a good amount in there. Then we're going to come back to our bracket and I'm going to pass my wire through. Then I can grab my socket. We're going to line it up, plug it in, give it a quick tug test, make sure it's not going to come loose. Now, we can use the provided hardware with our bracket to mount off our plug, and then we can secure any loose wires. And just like before, the nuts for this hardware are going to be the lock-in nuts. So we should just be able to hold them with their fingers and tighten up the screw using a flat blade screwdriver.The final step of our installation is going to be testing all of our circuits. Now, I went ahead and plugged up my tester, but you can also use your trailer at home. So if I turn on my lights and see that my clearance lights are working, my left turn signal, my right turn signal, my brakes, and we're even going to get our reverse circuit. And if we look at the needle on the top, it'll give us our voltage and that's because we're getting that 12-volt power source at the back as well. We currently don't have a brake controller installed in our Traverse, but it'd be extremely easy to add one later on and we can have all of our brake functions going to our trailer as well.But now that we know that everything's working, we can hook up to our trailer and hit the road. That'll finish up your install and your look at the Tekonsha T-One Vehicle Wiring Harness with the seven blade RV-style connector on our 2019 Chevrolet Traverse..
