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.
