An ignition switch accessory terminal can be verified by measuringthe terminal while operating the vehicle’s key switch. With the ignitionkey in the “accessory ON” position, the terminal voltage should measurethe vehicle’s battery voltage. With the switch in the “OFF” position, itshould measure near zeroStereo MuteIf the vehicle’s stereo system supports an external muting feature, routeand connect the orange wire to the car stereo system.
