the harness i have was ordered for a pioneer 900bt so it is basicaly the same and seems to work but i dont have a green option for the parking brake wire..can someone please tell me which pin hole the parking wire is in so i can ground it to make the bypass work properly..at

present it flashes on for awhile then the green screen pops up saying driving prohibited ect..im assuming its because the parking wire isnt hookeed up right..a pic would be great of where exactly the parking brake wire is..ty
