C. Positive reversal switching to factory
actuators — The factory door lock switch
typically has 5 wires. Two wires always show
ground, and one always shows +12VDC.
The LOCK WIRE shows ground at rest and
during unlock, but shows +12VDC when the
door is locked. The UNLOCK WIRE shows
ground at rest and during lock, but shows
+12VDC when the door is unlocked. Many
GM trucks, Fords, and Chryslers use this
system. See fig. 18.
D. Single wire, polarity switching — The factory
door lock switch uses a single wire to control
the door lock and unlock operation. The
single LOCK/UNLOCK WIRE shows ground
when the doors lock, and +12VDC when
they unlock. This is found on most Mercedes
Benz and on some other European cars.
See fig. 19.
E. Single wire, positive shunt switching — This
system uses a single wire to activate the door
locks. Ap12VDC on the LOCK/
UNLOCK WIRE causes the doors to unlock,
and removing the +12VDC (not applying
ground) causes the doors to lock. Found on
some Ford Probes. See fig. 20.
F. Single wire, negative shunt switching — This
system uses a single wire to activate the door
locks. Applying ground on the LOCK/
UNLOCK WIRE causes the doors to unlock,
and removing the ground (not applying
+12VDC) causes the doors to lock. Found
on some Mazdas and Nissans. See fig. 21.
G. Aftermarket door lock actuators — If the
vehicle does not have power door locks,
install aftermarket actuators according to the
supplier’s instructions. (If the vehicle has
power door locks on all doors except the
driver’s door, install one aftermarket
actuator on the driver’s door. Includes some
Volvos, SAABs, and assorted Japanese
models.) See fig. 22.

To install the included patented dual-stage
electromagnetic shock sensor:
A. Cable-tie the sensor securely to at least two
points under the dash. Do not screw it to
metal. Mount so you can reach the
adjustment pods. (NOTE — The shock
sensor is omni-directional. It can be
mounted at any angle.)
