I am rewiring my car and getting close. I have a question as the FSM wiring diagram is confusing me. Back of my switch has a P, B, and R. I know R and one side of P go to the wiper motor itself, and B is 12 volt in, just not sure about the other side of P. The wipers work just fine and go back to park without anything connected to the other side of P, but it 12 volts when key is in, not sure what to do. tia
