qmant123 Posted 2 hours ago Share Posted 2 hours ago For the steering wheel buttons on volume up/down, source, and the phone/talk, are they just sending a constant 12v signal to the end of the wire harness, or is it different electrical pulses that the radio then interprets for volume, source, and phone/talk?
