How to Install a Trailer Brake Controller on a 2014 Jeep Grand Cherokee

Today on our 2014 Jeep Grand Cherokee, we'll be installing the Tekonsha Prodigy P3 Brake Controller, part number 90195. We'll be doing this in conjunction with the Tekonsha Plug-and-Play Direct Fit Wiring Harness, part number 3045-P, designed to plug into the Jeep Grand Cherokee tow port. It displays a no trailer connection until we plug it in. When it's connected, we'll see it boot up. It indicates we're in Boost 1 trailer wiring connected. We can adjust the gain as necessary or go through the menu display for the brake type.

We can also go through the boost settings from off, to 1, 2, or 3. Here at the bottom, we have the manual sweep which allows you to apply the trailer braking without touching the vehicle brake pedal. Here's our direct fit wiring harness. The gray end will match up with the manufacturer's gray plug. Go ahead and plug directly into it. Then, once plugged in, we'll go ahead and route the remaining portion of our harness over to where we'll be mounting the brake controller.

Keep in mind to stay away from any moving components such as the gas, brake, or parking brake pedal, or even possibly the steering column when routing your wire. As we route the wiring harness, we'll go ahead and take the zip ties and secure it as necessary. With the wiring harness installed, we'll attach the brake controller bracket using the 2 screws provided. On this application, we'll mount the plastic brake controller holder using the 2 screws, 1 on each side. Now we have both brake controller brackets in place, we'll mount the brake controller. First, take the wiring harness and plug it into the back of the brake controller.

Then we'll mount the brake controller into the bracket. There you have it for the installation of the Tekonsha Prodigy P3 Brake Controller, part number 90195, in conjunction with the Tekonsha Plug-and-Play Direct Fit Wiring Harness, part number 3045-P, on our 2014 Jeep Grande Cherokee. .
