On my Bv9348B which wires do I use to connect the steering wheel interface? There is no key 1 or key 2 just a key ground and key acc. I have a 2005 Ford focus with a steering wheel control + and - set of wires. Can I just directly connect the focus wires to the head unit wires?
after weeks of trying I have steerng wheel controls again. The instructions from boss were correct, the problem was the raptor wiring harness which was not pinned correctly.
trying to use an ASWC-1 but no luck so far.
