One Wire Multiplexing Door Locking Systems
Some vehicle's (Chrysler, Mazda and Ford Probe and others) use one wire to lock and unlock the doors.
Example: When the door lock controller sees a signal thru a resistor it will unlock. If a signal is received
without a resistor the doors will lock. Some use 2 resistors. One for lock and one for unlock. We have
developed patented plug-in fuse resistors for this application. Simply remove the fuse from our door lock
module and replace with correct resistor value fuses that matches the vehicles door lock switch.
Wiring:
1. Connect both the green (lock) and the blue (unlock) wires to the vehicles one wire lock/unlock wire.
2. Connect our violet polarity input wire to +12v or to ground. To match vehicles door lock polarity.
3. The white and the brown wires will not be used.
