In order to install brake controller wiring on the vehicle it needs to be connected to the trailer 4-pole harness and routed to the front of the vehicle. All the components required to route the wires from the rear of the truck to the front are including in the Tekonsha Prodigy brake controller kit.Continue Reading
Use these following steps in order to properly wire a Tekonsha Prodigy brake controller.
A standard trailer plug has a 4-way connector, that supplies power to the brake lights and turn signals. The 7-way connector allows three extra wires to power the brake controller. Connect the 7-way connector to the 4-way plug using an adapter.
Take the ground wire and screw it into the chassis of the vehicle.
The kit contains a duplex cable that connects to the two remaining wires of the 7-way connector. Use butt connectors to connect the 12-volt and brake wires.
Route the duplex cable from the rear bumper to the engine bay. Be sure to avoid any hot areas under the chassis, or other places that can cut the wiring.
Mount the brake controller inside the car and connect the brake wire to it. Connect to the 12-volt hot lead to the positive post on a battery using a small 30-amp breaker.
The last wire will be from the brake controller, which will connect to the brake switch. Find a wire that turns hot when the brake pedal is engaged and splice it into place.
