How to Install a Trailer Wiring Harness on a 2011 Chevrolet Equinox

Today on our 2011 Chevy Equinox, we'll install the Curt T-Connector 4-pole Wiring Harness, part number 56094. First, we'll open up the rear cargo door and then we'll remove the driver's side tail light assembly. To remove the tail light assembly, we'll remove the two fastener caps and set them aside and then remove the two fasteners. Now, we'll simply remove the rear tail light assembly by gently prying and pulling on the tail light assembly until it pops free from its alignment fasteners. Be careful not to break these alignment tabs as you remove it. Now, we can go ahead and remove the manufacturer's wiring from the tail light assembly.

We'll press on the connector lock and then remove it from the tail light, setting the tail light aside. Next, we'll go ahead and take the new Curt T-connector, the yellow and brown wire connector, and feed it from underneath the vehicle up behind the driver's side tail light assembly between the sheet metal and bumper cover or fascia of the vehicle. Now, we can go ahead and take the main connector and plug in to the manufacturer's wiring and the opposite end will go into the tail light assembly. With our connection made here on the driver's side, we'll go ahead and reinstall the driver's side tail light assembly. Next, we'll go ahead and remove the passenger's side tail light assembly in the same manner we did for the driver's side.

Next we'll go ahead and get underneath the vehicle and start routing our 4-pole connector to the center of the hitch and the green wire connector over to the passenger's side and up behind the passenger's side tail light assembly. Now with our wire over the passenger's side, we'll take the white wire with the pre-attached ring terminal which will be our ground wire for our 4-pole connector and attach it directly to the body of the vehicle. A quick tech tip: Finding a location with a sheet metal doubles up usually secures the ground screw the best. Using our self-tapping screw, we'll go ahead and make the attachment out. Next, we can go ahead and take the green wire connector, plug into the tail light assembly and then connect to the manufacturer's wiring and reinstall the passenger's side tail light assembly.

Now with everything reinstalled here on the passenger's side, we're ready to get underneath the vehicle, complete routing our wires and securing it with black zip ties. A quick tech tip: I also like to take some black electrical tape and wrap up about the first 12-14 inches of the 4-pole connector just to protect it from any road debris. Once you have your wiring secured, we'll go ahead and take a pair of side cutters and cut of the excess from our zip ties to clean up our install look. That will complete the install of our Curt T-Connector, part number 56094, on our 2011 Chevy Equinox.
