Trailer Brake Control in Diesel MH

[rcjays]

I have a 2001 Holiday Ramble Endeavor Diesel MH. It has Air Brakes. I want to tow a medium size flat bed trailer. I plan to install a Tekonsha P3 Control. Can anyone give me instructions on how to wire this into my MH. Generally the control is linked to the brake switch, but air brakes don't have regular brake light switches. What do I tie the sense wire into?? JDA Thanks

Tie it into the circuit that goes to your brake lights. If your lights are al combined so that the turns and brake lights use the same filament, you can tap in at the turn signal.
