How to Install the Curt T-Connector Vehicle Wiring Harness on a 2019 Chevrolet Traverse


Rob: Rob here at etrailer.com. Today we'll be taking a look at the Curt T-Connector Vehicle Wiring Harness with a seven-way RV style connector on our 2019 Chevrolet Traverse. Our Curt wiring is going to give us all seven functions at the back of our Traverse. We'll get all of our lights, like our taillights, turn signals, brake lights, and our reverse lights. But we're also going to get a 12 volt power source back here, and a brake controller circuit, if we want to add one later. We're going to have a nice spring-loaded door so you can keep all that dirt, debris and moisture outside of the connector.

There's also going to have a nice gasket in there so when it is sealed up we don't have to worry about anything seeping inside.Now, if you look at the doors here, it does have a little latch. That's going to hook onto your seven-way cord itself and prevented from getting pulled out when we're driving down the road. One of my favorite things about this wiring is how easy it's going to install. A lot of customers don't want to cut or splice into the factory wiring and for good reason, I don't want to do it either. But our Curt wiring is going to plug directly into a factory tow package plug behind the bumper.

Honestly, that's going to be the hardest part is just getting to it because we simply just plug it in, route it over towards our hitch and mount it up. In fact, let's go in and walk through everything together and I'll show you exactly how easy it is.To begin installation we want to come to the back of our Traverse. Now, we have a hitch installed and it's behind this panel. We need to remove that panel. We've got two turn knobs at the very bottom corners, we'll turn them counter-clockwise.

We'll grab our panel and we'll lift the whole thing up and then we can pull it out and down and pull the panel away. Now, ideally you want to mount your seven-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 seven-way. We're going to be using the Pollak 7-Way Mounting Bracket. It'd be a good idea to pick one of these up because the slot and the holes are going to make it really easy to mount your seven-way.

We're not going to have to worry about getting a specific one.I'll take the hardware and loosely get one started so I have to worry about the bracket falling down. Then we'll put the other screw and nut in on the other side. I'm going to come back with a 10 millimeter socket and since these are locking nuts, we should just be able to hold it with our finger and tighten up the 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. It's 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. You want to pull down that red tab to unlock it. 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, it's going to be on the cap. I'm going to pull it out, 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 I'm 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. Now, I've run it all the way over to where my other plug is. I'll take a little bit of dielectric grease and I'm going to fill this cavity up and hopefully it'll prevent any moisture or corrosion buildup inside the plug. We don't have to worry about any bad connections. We'll take our plug now we're going to plug it into our tow package harness.Once you have it plugged in, you want to make sure that it's locked in place. It's a good idea to give it a quick tug. 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. I'll put some dielectric grease on the seven-way end of our connector as well. Once we get a good amount in there, then we're going to come back to our bracket. I'm going to pass my wire through. I can grab my socket. We'll line it up, plug it in, give it a quick tug test to make sure it's not going to come loose. Now, we can use the provided hardware with our bracket to mount up our plug, and then we can secure any loose wires.Just like before the nuts for this hardware are going to be the locking nuts so we should just be able to hold them with our fingers and tighten up the screw using a flat blade screwdriver. The final step of our installation is going to be all of our circuits. Now, I went ahead and plugged up my tester, but you can also use your trailer at home. 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 a reverse circuit. 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. We can have all of our brake functions going to our trailer as well. Now that we know that everything's working, we can go ahead and hook up to our trailer and hit the road. That'll finish up your look and the installation of the Curt T-Connector Vehicle Wiring Harness for the seven blade RV style connector on our 2019 Chevrolet Traverse..
