I have an old style AVC-R and need help finding out what wires do what.
it only has 3 wires to connect to the car and 2 for the solinoid i know what ones are for the valve but i dont know what the other 3 are, they are:
Black: im guessing ground
Red: power i think, but not sure if it is constant or ignition?
Green: i have no idea??
