I do not offer a brake controller wiring harness for a 2005 Bounder RV with a Freightliner chassis that will plug into the Tekonsha Prodigy P2 Brake Controller, part # 90885.

Usually on an RV there is not always a factory brake controller plug under the dash and if there is it can vary between different models so there is not always a location listed. You might check with the RV manufacturer and see if they can help you locate the brake controller wiring harness on your RV. Some RVs will use a Ford brake controller wiring harness, but you would have to find out from the dealer what model year harness will work on your RV.

If you have a 7-Way connector on the rear of your RV and no factory brake controller harness you will need to connect the blue brake controller wire from the 7-Way to the blue output wire on your brake controller. The white wire on the brake controller is grounded to the negative terminal of the vehicles battery. The red wire on the brake controller will need to be connected to the cold side of the brake stoplight switch, above the brake pedal, which will only show power when the brakes are applied. The last wire on the brake controller is the black power wire which will be need to be connected to the positive terminal of the vehicles battery via a 20-amp (or 30-amp) inline circuit breaker.

I am including a link to a FAQ page on brake controllers and a link to a FAQ page on brake controller installation from scratch if you do not have a 7-Way on your RV.
