type B: negative-triggered, relay-driven system
This system is common in many Toyotas, Nissans, Hondas and most European Ford
vehicles.
The switch will have three wires on it, and one wire will test ground all the time. One
wire will pulse negative (-) when the switch locks the doors, and the other wire will
pulse negative (-) when the switch unlocks the doors. This type of system is difficult to
mistake for any other type.
I I M M P P O O R R T T A A N N T T ! ! Remember that these wires' functions reverse between Type A and Type B.
