I've installed a new system with one of the things being a PAC SWI-PS for my steering wheel control. It says to tap in to the green wire on the steering column. Guess what. There's more than one green wire. I unplugged one with the factory unit in place and steering wheel controls still worked, so I eliminated the easy one. geez. Anyway, anyone done this and confident about which one it is?
