One Wire Multiplexing Door Locking Systems
Some vehicles (Chrysler, Mazda 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.
ALA-DL1 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.
