How to Install a Trailer Brake Controller on a 2013 Chevrolet Avalanche


Today, on our 2013, Chevy Avalanche, we'll be installing the Tekonsha Brake Controller, Part Number 90885. To begin our install, we'll go ahead and mount the brake controller bracket. For this application, we're mounting here on the driver side to the left of the steering wheel. Once we have the bracket or pocket secure, we can then go ahead and locate the manufacturers towing harness. This will be up underneath the dash here on the driver side between the parking brake pedal and the brake pedal. You'll notice there's a white tape going around it, securing it to the manufacturers harness that has a black electrical tape wrapped around it. These wires will be exposed. We'll go ahead and cut the tape and pull the wires down to gain access to them.

We'll be connecting these to our brake controller harness that comes with the brake controller. Now, you can see with the brake controller and mounting location and the length of the wires, we can go ahead and trim some excess of both sides. Once we trim them off, we'll go ahead and strip back the wires of the pigtail and then add the butt connectors. Now, we'll go ahead and strip back the manufacturers wires and then secure them to the butt connectors. Starting with our ground wire, it will be white to white from our pigtail to the manufacturers harness. Then we'll do the brake signal switch, which will be the red wire for the brake controller pigtail and then light blue wire with a white tracer for the manufacturers harness. Next, we'll connect the power for our brake controller; it will be the black wire coming from our pigtail and then red wire with a black tracer for the manufacturers harness.

Then finally, we'll connect blue to blue from pigtail to harness. Now with all our connections made, I recommend to wrap it up with some black electrical tape. This will help to clean-up our install look and keep out any dust, dirt, debris. Once that's done, we can then route the wire to the brake controller pocket and we'll go through the pocket and secure it to the brake controller. Once we make this connection, we can put the brake controller in position in the pocket, and then we'll take some black zip ties and secure the wiring underneath the dash. Now, we'll go ahead and cut off the excess by the zip ties to clean up the install look. Next, we'll go ahead and move to the engine compartment.

Here, we'll need to remove the fuse box cover. Once we remove the cover, looking between the fuse box and the driver side fender well, you'll see a red wire that's taped to the manufacturers harness. We'll need to cut this free. Using a utility knife, we'll go ahead and cut the electrical tape and pull the wire free. We'll route it to the front of the fuse panel where there is an open post. We can secure the pre-attached ring terminal to.

To do this, we'll be using a 8-millimeter nut, Part Number 185917. Then once we go ahead and thread it on, we'll tighten it down and then use a black zip tie to secure the wiring. I'll cut off the excess from the zip tie and re-install the fuse box cover. That's it, we're ready to hit the road. That does it for the install of our Tekonsha Brake Controller, Part Number 90885 on our 2013 Chevy Avalanche.
