Brake Controller Recommendation for 2008 Jeep Grand Cherokee with Factory 7-Way

Question:

I have a 2008 Grand Cherokee with the 3.0 CRD. I just bought a 30ft travel trailer. Came with weight distributing hitch and some other non relevant extras. The Jeep has a factory 7 pin hookup but I cannot find anything under the dash that would indicate a factory plug in for a trailer brake controller. Being that the trailer is 5500lbs dry, and a tandem axle, I refuse to tow without trailer brakes. Im wondering what controller would be best suited for my application and looking for some insight into where I could find the hookup for said controller. Thanks!

Since your 2008 Jeep Grand Cherokee has a 7-Way you will only need a few more components to complete a brake controller install on your vehicle.

First let's start with a brake controller. I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to set up.

Next, for a wiring kit to install the brake controller to the 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied and none when not applied. This will be the circuit you will run the red wire to.

Finally you will need to run a length of 10 gauge wire (part # 10-1-1) from the brake output circuit of the controller to the brake output circuit of the 7-way (blue wire). The # 10-1-1 is sold by the foot so you will need to order a quantity of the amount of feet you will need.
