Trailer Wiring Harness Installation - 2004 chevrolet impala - Etrailer

Today we are going to be installing a 4-pole, part number 118002, on a 2004 Chevrolet Impala. OK, we are inside the trunk area, and we want to go ahead and access the wires that we are going to be tapping into for our wiring harness. Those wires are actually located directly behind the tail light assemblies on both sides of the vehicle. In order to gain access to those wires, we are going to need to go inside the trunk area and we will first off need to remove these three screws per side and then pull back our carpeting. And you can actually see there are two more set screws that we are going to need to remove as well. And with all the set screws removed, I can go ahead and pull the tail light assembly off. As you can see, here is our main wiring harness, feeding the drivers side tail light assembly here. We have got three wires here. We have got a brown with white, which is going to be the running light lead that we are going to be tapping into the yellow, which is our left turn and left brake signal and then the black, which is the standard ground. And then what we want to do is to take our yellow wire here off of our wiring harness, and we want to go ahead and we are going to attach it directly to the yellow wire on our tail light assembly. We are going to use the quick splices that are provided in the installation kit, and what we want to do is just take the wire that we are attaching to - which is the yellow here on the harness. We are just going to slide that into the first opening. And we are going to take our yellow wire from our 4-pole and slide it in. There is a little stop in here in the inner side, so just slide it in until it hits the stop. And then you just take a regular pair of pliers and crimp down the little metal tab, and that will make our connection for us. And then we just flip the cover over, and our connection is made. We are going to do the same thing with the brown wire - again, the brown and white stripe. We are going to connect that directly to the brown wire on our 4-pole. What we have left are our white and green wires. The white wires are ground the green is going to be our right turn/right brake. There is a ground wire here on the harness, but I would definitely recommend you ground directly to the back side of the tail light assembly here. What I have done is actually stripped off a little bit of the end to expose the wire, and I am just going to use a small ring terminal, slide that directly onto here, and crimp it down. And then I am just going to take a regular self-tapping screw and screw that in behind the tail light assembly here.
