I cooked this one up in my mind for a while and just got done with the install. The PO installed a nice headunit in place of the original Becker and in doing so, he took the Fader wheel out of the circuit.

Well, I decided to put the fader switch to use once again. Excuse the mess in the floorboard, I got excited and made a video before cleaning up.
