Depends a little on your brake controller - if it's a regular old inertia- or digital-style, wire it up to the brakelight switch and you're good to go, same as a pickup. If it's a Brakesmart, they make a kit to use line pressure off the pedal circuit instead of fluid pressure, not really sure what it consists of, but they do have it. If it's one of those with a positioning cable off the pedal linkage (forget the brand name), you might have some fab work ahead of you, but it should work about the same. The only one that's probably a no-go is an old-style that uses fluid pressure directly on the rheostat - I don't think it'd work very well on air pressure. Good luck!
