This system is common in many Toyota, Nissan, Honda, and Saturn models, as well as Fords with remote-con-
trolled door lock/unlock (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.
IMPORTANT!
Remember that the functions of these wires reverse between Type A and Type B!
type B: negative (-) pulses from the switch to the factory relays
