I'm trying to hook up my parking bypass to my Pioneer head unit. I get that you need to connect the green, blue, and black wires, however I am confused as to how to connect the black and blue wires. All the wires except the green are connected to some white connector that connects to the vehicle. Do I need to strip the black and blue wires in the middle and connect the parking bypass to those. Or do I need to remove the black and blue wires from the connector and connect the ends to each other?
