the sedan's headlight wiring is ground switched... which means 1 common power source, and 2 grounds which the control stalk controls
the P5's LOW beam wiring is power switched, and the HIGH beam wiring is ground switched... this makes it so that when you turn on the high beams, both low and high beams are on... you MUST undo this when you rewire it for the sedan's single bulb setup, otherwise you will burn up the bulb!
