Brake Controller Wiring Instructions for a 2005 Jeep Liberty Renegade with Factory 7-Way Tow Package
Question:
Hello, I have a 2005 Jeep LIberty 3.7 renegade with a factory tow package including a 7 pin wiring plug. I would like to install a brake controller for towing a 19 camper trailer. Is there a certain model or kit that will allow me to plug in a brake controller with out having to cut or splice any wires? I thought maybe it would already have a wire under the dash for the brake controller? Thanks!

You will need to do some hard wiring when installing a brake controller on your 2005 Jeep LIberty 3.7 renegade. Jeep typically runs a light green wire from the 7-way, at the rear of the vehicle to the passenger compartment to carry the output from the brake controller. This wire can be found under the dash to the left of the steering column or sometimes behind the kick plate on the left side of the foot well. This green wire would attach to the output wire of the brake controller, which is the blue wire. A good choice for a brake controller for your Liberty would be the Prodigy P2, # 90885.
The three remaining wires would need to be connected. The black wire on the controller supplies 12-volt power to the controller. It would attach to the positive battery terminal via a 20- or 30-amp circuit breaker. The instructions from your brake controller will state which is needed. The white brake controller ground wire attaches to the negative battery terminal. The red wire taps into the brake stoplight switch located at the top of the brake pedal. The switch can have several wires exiting it, use a circuit tester like part # PTW2993 to locate the wire that only shows voltage when the brake pedal is pressed. Normally on the 2005 Liberty this wire will be a white wire with a tan tracer on it. Once found, tap the red wire into this circuit.
We offer a brake controller install kit, part # 5506 that includes the circuit breakers and the necessary 10-gauge wire to connect the controller to the battery. Ring connectors and other hardware are also
included.
You could go with the ETBC7 brake controller installation kit, but because you already have the 7-way on the rear of the vehicle, you will not need everything included in that kit. I attached installation instructions for this kit for you, because they can be very helpful for wiring the brake controller.
