Type F: One-wire system - cut to lock, ground to unlock.
This types of central door locking system mainly for Japanese driven
Single wire in series negative trigger.
Single wire that pulses negative to unlock, and open circuit to lock.
This type of door lock system usually requires a negative pulse to unlock, and cutting the wires to lock the
door.( for some vehicles, these are reversed).
Type E: Electrically-activated vacuum systems.
Polarity reverses on a single wire to lock and unlock. Please set the door lock/unlock time to 3.5 seconds.
The vehicle must have a vacuum actuator in each door. Making sure that locking the doors from the
driver’s or passenger side using the key activates all the actuators in the vehicle. This requires a slight
modification to the door lock wire harness.
The door locks are controlled by an electrically activated vacuum pump. The control wire will show +12v
when doors are unlock and (-) ground when locked.
NOTE: For this kind of central door locking, must program the lock pulse time to be 3.5 seconds.

Type G: Positive (+) multiplex. One wire controls lock and unlock using resistor(s).
Single wire positive central locking
Single wire, positive lock, positive unlock.
Two potential (resistor may require) positive trigger.
Single-resistor style: if one resistor is used in the door lock switch/key cylinder, the wire will pulse (+) 12V
in one direction and less than +12V when operated in the opposite direction.
Two resistor type: if two resistors are used in the factory door lock switch/key cylinder, the switch/key
cylinder will read less than +12V in both directions.
Determining the proper resistor values: to determine the resistor values, the door lock switch/key cylinder
must be isolated from the factory door lock system. For testing, use a calibrated digital multi-meter that is
set to ohms.
IMPORTANT: to ensure an accurate resistance reading, do not touch the resistor or leads during testing.
1.Cut the output wire from the door lock switch/key cylinder in half;
2.Test with the meter from the switch side of the cut door lock switch/key cylinder wire to a reliable
constant +12V source. Some good constant +12V references are the power input source to the door lock
switch/key cylinder, the ignition switch power wire, or the (+) terminal of the battery.
3.Operate the door lock switch/key cylinder in both directions to determine the resistor values. If the multi-
meter displays zero resistance in one direction, no resistor is need for that direction.
4.Once the resistor value(s) is determined, refer to the wring diagram for proper wiring.
