TYPE B NEGATIVE TRIGGER
Type B: Negative trigger with three-wire (-) pulse controlling factory lock relays.
Two wires resting open circuit, one pulses ground for lock and the other pulse for unlock.
For this kind of trigger, the vehicle switch will have three wires on it, 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.
There are 3 wires(+) pulse controlling factory locking relays, one pulses 12v for lock, one pulse 12V
for unlock, the last one is for constant 12V. Extra 2 SPDT relay are required.
Type A: positive trigger with three-wire (+) pulse controlling factory lock relays.

Motor interrupt central locking:
Type C Reverse polarity, positive triggered
Two wires resting at ground, one pulse 12V for lock, the other pluses 12V for unlock
Direct-wired reversing-polarity switches. The switches are wired directly to the motors. This type of
system has no factory relays. Extra 2 SPDT relay are required.

Type D: Adding one or more aftermarket actuators
For this type of vehicle, there isn’t a motor in the driver’s door (central locking only operates from
the driver’s door). An extra door actuator is required.
Vehicles without factory power door locks require the installation of one actuator on each door. This
require mounting the door lock actuator inside the door. Other vehicles may only require one
actuator installed in the driver’s door if all door locks are operated when the driver’s lock is used.
These include central locking systems without an actuator in the driver’s door, but with factory
actuators in all the other doors. Type D also includes vehicles without power locks, which will have
actuators added.
