I have a Kenwood KDC-BT958HD put in. I just wired up the speakers and the sub last night. But I still have to steering control to do. The Third Ford harness still has a green/white, TWO yellow/browns, and a white/black wires left on it which go to the steering control I think. I have a wire on my Kenwood harness that is for the steering wheel control I just need to know what wires go to it and if there needs to be a power wire sent to the steering control and if that should be from the battery or the ignition. Thank You.
