One other question -
I'm using the Peripeheral Steering wheel control adapter. the wiring instructions are manure - Any clues on how to run it? I have a black to ground a red to the 12v switched and a green wire that needs to go to the controller.
The instruction say -
Quote:

Connect the INTERFACE's Green wire to...pin # A7 (blue) of the above connector
Connect pin # A6 (purple) to accessory +12v

Do I need to jump over the OS2 Bose adapter and go straight to the cars harness coming into the new harness? I dn;t under stand why I'd connect the A6 (purple) from the car to the +12v. That seems weird.
