To respond to Koliver, That might work fine going down a short hill or if your trailer brakes are worn or out of adjustment but if you are going down a long grade and using the pacbrake then the trailer brakes will be on the entire time and burn them up.

Thanks for the suggestions. When I contacted pacbrake technical department I was a bit concerned when he told me he was unaware that the brake lights were activated when the pacbrake was turned on. They are going to do more research and get back to me. One of the easiest solutions might be to disconnect the relay that activates the brake lights when the pacbrake is turned on, but I dont know where to find that relay.

It is an aftermarket electric brake controller mounted under the dash just like you might find in a pickup truck. I'm not sure where this is wired in but normally they attach right after the brake switch on the pedal. So when the pacbrake is activated it activates the brake lights which sends power to the aftermarket brake controller, there must be a solution to this.

Just purchased a 2005 Fleetwood Excursion with Cat C7. The first time I used the coach I was pulling a heavy 3-axle trailer going down a steep grade. I switched on the Pacbrake, and when I looked back, my trailer brakes were smoking. I had to reach down and turn off the trailer brakes, which wasn't a really good thing to do. I believe that the trailer brake is wired in somewhere near the brake pedal. I know when the Pacbrake is turned on the brake lights also come on. How do I keep the Pacbrake from activating the trailer brakes?
