Re: passenger door switch?
If its anything like previous model rangers it is a switch that screws (just turns a quarter to half turn and locks in place) into the bottom of your latch. At the top of this switch is pretty much a button that when the door is closed this button gets pressed (all happens inside the latch). When this button is pressed is just completes the circuit which tells the GEM that the doors are closed.
