Does anybody know if you have to run a wire for the brakes lites, because the brake buddy or simular devices, turn the brake lites on, or is that mainly for the turn signals?
Well, you have to run wires for the turn signals, and typically you run wires for the brake light as well while you're in there wiring the tail lights. That way you're insured that brake lights will work, even if something goes awry with your supplemental braking system (they ARE known to quit working from time to time).
I'm not sure if you could get by with relying on just your supplemental braking system to engage the brake lights, although some probably do just that. Check the various DOT laws where you'll travel, too, there may be a law or two requiring you to wire brake lights to the towing vehicle (Motorhome).
