Trailer Wiring Harness Installation - 2012 GMC Acadia
Today on this 2012 GMC Acadia, we're going to be installing Tow Ready Trailer Harness, part number 118451. The first thing we need to do is remove the tail lights. There are two screws holding in each tail light housing. We'll use a small flat headed screwdriver to pop open the covers and use a 7-mm socket to remove the screws and remove our two tail lights. Be careful as you pry the mount not to break off the positioning tabs or tear the wiring. With the tail light out, we'll go ahead and disconnect it from the vehicle's factory harness.

Today we are going to be installing wiring harness part number 118451 on a 2008 GMC Acadia. OK, we are here at the back side of the vehicle and the attaching points for our wiring harness are actually located directly behind the tail light assemblies themselves on both sides of the vehicle. So the first thing we want to do is to go ahead and remove them. There are two black caps on each one of the assemblies. You need to pop those back, and that will give us access to the fasteners that are holding the tail light assembly on. We are going to remove those fasteners and pull the tail light assembly off to gain access to the connectors themselves. We just take a little flatheaded screwdriver and pop that right back. And as you can see, there is a regular hex head screw in there. And you want to be careful when you are doing that to make sure you do not break the locking tabs. And we are just going to take a little 7-millimeter socket here and remove the bolts. With both screws removed, we want to go ahead and gently pry away the tail light assembly. There are two aligning tabs here on the back side. You want to make sure that those do not break. You just want to gently kind of wiggle it back and forth until they release.
