This door lock system is common in many Toyotas, Nissans, Hondas, and Saturns, 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.
IMPORTANT!
Remember that these wires' functions reverse between Type A and Type B!
type B: (-) pulses from the switch to the factory relays
