One Wire Multiplexing Door Locking Systems
Some vehicle’s use one wire to lock and unlock the doors. Some require 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
the ALA-DL1 door lock module and replace with correct resistor value fuses that matches the vehicles door
lock switch system.
Wiring:
1. Connect both the green (lock) and the blue (unlock) wires to the vehicles one wire lock/unlock wire.
2. Connect the 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.
