Installation: Connection points are located behind the taillights. The 4-pole trailer connector will be stowed under the vehicle close to the trailer hitch. A mounting bracket is recommended.
Tech Tip: It is always a good idea to apply a small amount of grease to all electrical connections to help prevent corrosion.

Today we are going to install part number 118396 from Tow Ready. We are going to install this T-1 harness on a 2005 Buick Tarazza. And also, we are going to use a bracket, part number 118144. First we will install our bracket. It is going to install to the factory bracket that is on the hitch. Now this bracket here, it can be installed like this on the hitch. Or, if you did not have a bracket on the hitch, you could easily attach this to the bumper. We will go ahead and start installing our T-1 connector. And we do have to get the tail lights off the vehicle, so we have to open up the back hatch to get to the screws to take off the tail lights. We will take off these two screws right here and then we just pop the whole assembly off. Once you have the tail light loose, go ahead and disconnect it from the wire harness. It is this connection right here you want to take apart. And then go ahead and repeat the same steps for the other side.
Next what we are going to do is our 4-pole in behind this cavity here behind the light and down out toward the bottom. Also, what we want to do is take the passengers side and push it down in there, too, and pull it out the bottom. The yellow side with the brown wire will always stay up here on the drivers side of the vehicle. In fact, we will go ahead and just snap that into place. All right, now that we have got our passengers side, we will go ahead and run that underneath the body, up to the other side. We will go ahead and install it into our bracket, push it on through, and just kind of work it until it catches those edges right here. And it will be secured it is basically a friction fit. We will leave that alone for now and continue with our other harness going back to the other side.
All right, we will take the other half of our harness, going back up to the passengers side, and just tuck it up in there as far as we can so we can pull it from the top. All right, go ahead and pull it out and just make your connection. And then take your ground wire and just screw it to the sheet metal right behind the tail light. Get it started, and then go ahead and finish it off with a hand tool so you do not strip it out. All right, let us go ahead and reinstall our tail light assemblies now. At this point, we have got our wires pulled back behind the hitch a little bit, and we will go ahead and just get our wires ready and we will set tie them to the back side of the hitch. And do the same thing for the other side, and make sure the wire has plenty of distance between the exhaust. All right, and that finishes our install of part number 118396 from Tow Ready on our 2005 Buick Tarazza.

Received the product quickly and was able to install this harness extremely quick. The instructions were easy to follow and it took me all of 15 minutes to hook up to my current brake lights. Could use a few more wire ties but other than that I am very pleased.13662
