Today we're working on a 2005 Chevy TrailBlazer. We're going to install the Tekonsha P-3 Brake Controller, product number 90195. Our first step is to remove the lower kick panel. There are several fasteners that will have to be removed. Ok, with our kick panel lowered we need to locate the manufacturer's wiring that we're going to connect to. This white tag is the indicator that we're looking for and then you can see the taped off ends here taped up to the manufacturer's harness.
We're going to go ahead and free those from the harness so that we can make our connections. Go ahead and remove the taped ends so we can strip them back and make our butt connections. Now that we've located our wires, I'm going to go ahead and take the pigtail that comes with our brake controller and install my butt connectors on it. The red wire coming out of our brake controller is for the brake signal. The white wire coming out of the brake controller is for ground.
The thicker dark blue wire is the brake signal that we're going to send to our sevenfold connector. Then a thicker black wire is the power to our brake controller. Each four of these leads will match up with the four leads that we just pulled out from the manufacturer's harness. Let's go ahead and strip these back and start making our connections. Now the four colors that come out of the brake controller will not match up exactly with the manufacturer.
The power from our brake controller is the black wire. The power from the manufacturer is the orange wire. The closest color match from our brake controller to the manufacturer is the thicker dark blue wires. As we said before, the white wire from our brake controller is the ground but from the manufacturer it's black. So we'll match the black wire from the manufacturer up with the white wire from our brake controller pigtail.
Then the brake signal that comes from the vehicle will match up with the red wire from our brake controller. With all my connections made I'm going to go ahead and take some black electrical tape and tape up my connections and the wires just to clean up the look of it. Now we've got our wires connected, we're all taped up, I'm going to go ahead and secure some of the extra wiring up underneath the dash with a zip tie then we'll feed our pigtail out. I'm going to reinstall my kick panel. We'll mount our brake controller in this area and then make our connection. Now we can go ahead and reinstall our kick panel. Now we can go ahead and install the mounting bracket. Now we're ready to go ahead and make the connection with our brake controller and install the brake controller on the mount. With our fasteners tightened down that completes the install of our Tekonsha P-3 Brake Controller, product number 90195, on a 2005 Chevy TrailBlazer. .
Today on this 2004 Chevrolet Trailblazer with factory installed tow package we are going to be installing the Tekonsha P3 brake controller part number 90195. The first thing I want to note before we do our installation is what exactly the factory 7-pole looks like on the back of the Trailblazer that is going to indicate whether or not this vehicle has the wires underneath the dash to hook the brake controller into. Looking at the rear bumper area here you can see the factory installed 7-pole is kind of underneath mounted at an angle and again it is mounted to the factory hitch as well. On the lid itself there is the GM logo printed on it, that is a kind of cut and dry indicator right there as well. If you have the factory 7-pole you will have the wires under the dash to hook your brake controller to, if you do not you are likely going to have to do a manual hardwire of the brake controller and you will need to purchase some other components. 00:50
Today on this 2006 Chevrolet Trailblazer we are going to install the Prodigy P2 brake controller part number 90885. The first step is to get access to the wire harness itself. There is a plastic trim panel right here along this edge that goes toward the front of the vehicle. There are two screws here and here that we have to remove so you can take it down and out of the way to get to the wire harness. From here it should just unsnap. Over here on the far left is the wires for the brake controller. They are taped up so you will probably have to pull them out a little and we have our four wires. 00:43
