I'm gonna try it. I bought an aftermarket, 12V switch with the intent of putting it in the stock location, and I do intend to use the stock brake pedal/arm.
I don't understand what you mean by "reverse" brake signal...I'm truly a brand-new, fell off the turnip truck yesterday-kinda electrical guy.
I purchased one of the Painless Wiring kits so I could just start from scratch, with updated wiring, plus will serve as a method to make me smarter on the electrical systems...at least that's what I keep telling myself. I just haven't had the time (nor inclination in this cold weather) to start on the wiring yet, but I hear spring could be on the way!
