Installation of a Wiring Harness on a 2000 Chevrolet Blazer
All right, today we are going to install part number 118002 from Tow Ready. And we are going to install this 4-Flat Car End on a 2000 Chevrolet Blazer. And we will show you how to mount it. It comes as a very simple kit. It comes with a 4-pole flat for the car end, and also four wire caps to tap into the wiring on the vehicle. What is really nice about the GMC Jimmy and the Blazer we have here is that the wiring harness is actually already provided for a towing package. They all have it, and it is located actually behind the license plate light right here, zip-tied to the back side of the bumper. So just cut the zip-tie, basically, pull it down, and all your wires are there, ready to go. And on the harness here, it actually tells you what wire does what function, so that is pretty handy. So what you want to do is go ahead and pull up the tape on the wires here. They are staggered, so you are going to go up pretty far to get to the ends of each wire.
OK, we have got our wires spread apart here, and we will go through the color code. The white is going to be ground, and this brown is going to be the running lights. And there are two greens: The light green is actually going to be reverse lights, and the dark green is going to be your right turn. We will go ahead and wire up the harness. Brown is going to be the running lights. The same circuit is going to be on our 4-pole, so we will go ahead and hook that up. Just snap it over one wire, and the second one uses a tap you just put it right next to it and squeeze it with a pair of pliers. Give it a good test and then just snip off your extra. Next we will work on our right-turn signal, which will be green here and is actually going to be dark green on the tow vehicle harness. There is a light green here - do not use that one. Get that out of the way. Use your dark green wire that will be right turn. We have shortened the wire so we can stagger our connections so it looks a little bit nicer. Ideally, when you are done you will not even see this. Next we are going to work on our left-turn circuit, which will be yellow. And on the tow vehicle harness it is going to be yellow, also. And our last connections is going to be our ground wire. So, white is going to be ground on our vehicle harness and white is going to be ground on our 4-pole flat.
Now these connections here, you can get by and probably sneak these on here like so. This gauge wire is a little bit heavy for this Scotch lock here, but it can be done. We will go ahead and do it here, but you might honestly be better off using a different type of connector. But we will just show it here how it would look. Once you have all your connections secured and all the excess cut off, you can go ahead and just tape everything up and make it nice and neat. As you can see, we just bundled the wires up to the original harness and ran just enough up to get out to the end of the hitch. All right, and with that, that covers our install of part number 118002 from Tow Ready.
