All right today, on this 2008 GMC Yukon, were going to install part number 90885 from Tekonsha. This is a Prodigy P2 Brake Controller. A little prep work before we get started, were going to take the wire harness that comes with the brake controller and add some bloom loom material to it which is part number 459075-1. Well use about 2ft of it. And then we went ahead and added the butt connectors to the end of the wires. We used the bigger yellow ones for the heavier gauge wires and the smaller blue ones for the ladder gauge wires.
All right now lets go underneath the vehicles stash and find the location of the wiring hook up to it. All right, now well go ahead and look underneath the dash to find a wire harness. And on this vehicle, its going to be located to the left of the steering wheel. Right behind this vent, we get the tag already pulled down, but chances are its going to be tucked up in there pretty far. Look for the wires with the blue wire and the red wire with a black stripe.
Youre going to get a good clue of what youre looking for. Well get the four wires to hook up to, so we can just go ahead and strip the wires and get started. Well start from white wire which is ground and then hook up to white on our brake controller harness. Go ahead and move on to our red wire to black stripe. Therell be a power supply from the battery.
Then hook up to the black wire coming from our brake controller. Now our blue wire will connect to our blue wire on our brake controller. This is the output to a trailer brakes. And our last wire will be our break signal, coming from the brake switch which is the blue and white wire; well go to the red wire on our brake control harness. We can go ahead and take these up, and then well go ahead and start mounting our brake controller.
Were going to use this pocket for the brake controller. Its got holes in the back where we can mount this up to the dashboard. And were going to use this location right here. Take your brake controller and install it into the pocket. Just give us a feel of where its going to sit. All right, were going to make sure that the brake controller is in a straight line front to rear with the vehicle and that its also not twisted as well. Take one of the sheet metal screws and well just put a pocket in place and make a mark with it. All right, well go ahead and reinstall our pocket. Just snug it up so we can make a mark for our second hole. Okay, make a mark and draw another hole again. Now we take our cable, run it through our bracket, and well plug it in to our brake controller. All right, well now go ahead and secure our wires up into the dash. Now we need to get underneath the hood and connect some wires. Now theres two wires we need to connect up. One wire will go to the brake controller; the other wire will go over a 12-volt feed and will going to about up back to the connector. This red wire right here, just take to the wire harness, just go ahead and pull it out, and that goes to our feed for our 12-volt power supply out back. In our other wire for the brake controller will get it right here. Now connections have to be made inside the junction box here, so well take the cover off and move it upward. And then all were going to do is go ahead and just hook up our wires to be repost right here. The two ring terminals match up to the two different sized studs. Now a hardware that you need to tighten these down does not come with the vehicle, you have to purchase those separately. The nut were using is a 10mm nut with a 1.25 thread pitch or larger of the two. This one is a 6mm nut with a 1.0 thread pitch. And then were just going to loosen them just a little bit, you dont want just pick the whole junction box from electoral components underneath, just enough we have access. Once weve verify we have power going to the brake controller, we can go ahead and reinstall the cover. While power going to the brake controller, we can go ahead and test it out over the trailer, and make sure we have received through our connection. And with that, that will finish it for our install part number 90885, Prodigy P2 Brake Controller on our 2008 GMC Yukon.
Today on our 2007 GMC Yukon well be installing the Tekonsha Brake Controller part number 90885. Keep in mind this setup is for a vehicle equipped with the manufacturers 7-pole. First, well go ahead and identify the manufacturers wiring that well be connecting to. As you can see here there is a red wire with a black tracer which would be the manufacturers power wire, a light blue wire with a white tracer which would be the brake switch signal circuit, a dark blue wire which will be the power feed to the 7-pole brakes and then a white wire for ground. Lets go ahead and pull them free from the manufacturers harness now. Now, we can go ahead and mount the brake control bracket.
Today we are going to install a brake controller on a GMC Yukon, a 2001 model, and we are going to be a brake controller using part number 90185. And we are also going to be using adapter part number 22283. All right, we are going to mount our brake controller on the bottom of the dash. And there is a steel component that is going all the way across. We will go ahead and mount to that. What we will do is actually take the bracket, find a position we like, and go ahead and clamp it into place. All right, we are going to use some self-tapping screws instead of the screws that came with the kit it is a little bit easier to drill into the metal. The screws that come with it are actually designed for plastic.
