ok....i figured it out. its fricken simple. if anyone wants an exhaust brake, but doesnt want to go through all the crap to wire it up to the brake pedal, and doesnt want it plugged in anyway, because it comes on at the wrong time (thats what mine did) or whatever. all you need to do is wire up a 12V switch and run 12v to the gray/red wire. you just cut the gray/red wire and solder on the 12V switched wire. you can leave the ground hooked up. just do something so the cut gray/red wire doenst short out. so basically you just send a 12v signal to the gray/red wire and it closes. cut the power and it opens back up. its a lot simpler than going through the other crap for the brake pedal.
