type B: negative-triggered, relay-driven system
This system is common in many Toyota, Nissan, Honda, and
Saturn models, as well as Fords with the keyless-entry system
(some other Fords also use Type B).
The switch will have three wires on it, and one wire will test
ground all the time. One wire will pulse (-) when the switch
locks the doors, and the other wire will pulse (-) when the switch
unlocks the doors. This type of system is difficult to mistake for
any other type.
