How to Install a Trailer Wiring Harness on a 2010 Chevrolet Equinox

Today on this 2010 Chevrolet Equinox we are going to install part number 56094 from Curt. This is their T-connector wiring kit. The first step involved, open up the rear hatch and we are going to have to get to the rear tail lights. Right now we are looking at the driver side tail light and what is going to happen is we are going to take off these two covers here and these have fasteners behind it to disconnect the tail lights. We are going to do this on both sides of the vehicle. Be careful when you pop these off, they can be kind of fragile. These will just pull off. Now to disconnect our tail light we are going to disconnect its junction point right here. Push down on this tab right here and it should come right apart. Now we are going to go over to the passenger side and do the exact same thing. 00:50

To start installing our T-connector harness we are just going to take our 4-pole and it behind the bumper cover and out the bottom. I have got two T-connectors here. The one with the yellow and brown wire is going to stay over here on the driver side. The green wire and the white ground wire is going to go below underneath the vehicle over to the passenger side. So we are going to take this part and it down through the tube. For the T-connector here for the driver side we are just going to push them together and leave it like that and this other half is going to plug back into the tail light. We can reinstall the tail light. It just snaps back into place, get the tail light back in. Put the caps back into place. Now lets go underneath the vehicle and route our wires across. 01:44

Now we are going to take our passenger side T-connector and our 4-pole and we are going to route it behind the bumper cover across to the other side of the vehicle. The 4-pole itself of course will stay by the hitch. We are just going to pull that through and leave it like that for now and continue on with our T-connector going across to the passenger side. Take the T-connector and just push it up as far as we can and reach from the top down and pull it out. If you can not push it up far enough to reach it to the top you can use a piece of wire and grab a piece of the wiring harness and just pull it on up. We have got the connector, just like the driver side we will just push it back together and then with our ground screw we will attach it to the sheet metal right here. We are going to use a self tapping screw to attach to the sheet metal. 02:57

Lets reattach the light just like we did on the other side. Lets go back underneath the vehicle and tie up our wires. We will start off by taping up our electrical bundle. Just make it nice and neat and go up as far as we can with it. We will slip on our little 4-pole cover right here, just pull over and pull the cover around the chain loop and we will leave it like that for now and we will bundle up the rest of our wires. There is a nice little hole in the sheet metal right here that we have got to attach our wire to. One on each side for that. It might be a good idea too to run the zip tie around the hitch itself to secure the wiring to the hitch. We will just trim off our excess and we will be good to go. All that remains now is to test the install with a light tester first and then we can try it on the trailer. Take the ground clamp and go to the ground on the 4-pole. We will start off by testing the running light circuit and turn on the headlights. Then we will try the left turn signal. Then we will try the right turn. Now we will do the brake signal which we should have constant green and yellow wires. That verifies that our wiring harness is working and then we can try it on the trailer. With that, that will finish our install of part number 56094 from Curt.
