The best procedure for installing the Tekonsha Prodigy P2 Brake Controller, part # 90885, on your Fleetwood Motorhome with a Freightliner chassis is to follow the Brake Controller manufacturers instructions.
I contacted our representative at Freightliner, he informed me that if the motor home is a 2004 or newer there is a 6 pin connector under the dash that will be labeled either "TRBRK" or "TBC." This connector can be removed and the wires can be hard wired to the brake controller.
If the motor home is older than 2004 you will have to pickup the Brake Signal off of the Treadle Valve at the back of the Brake Pedal. The Treadle Valve is a valve that is operated by the Brake Pedal and directs air pressure from the dry reservoir tank to the brake chambers. The Treadle Valve also has a pressure switch that activates the brake lights on the rear of the vehicle.
If your motor home is older than 2004 I would recommend getting the brake controller installation kit # ETBC7, which includes the a 7-way, as well as everything else you will need to complete the brake controller installation. You may need some extra wire depending on the length of the motor home, part #10-2-1.
