will be grounded regardless of the switch's position. Of the two remaining wires, one will show
12 volts positive when the switch is pushed to "lock", and the other will show 12 volts positive
when the switch is pushed to "unlock".
These two wires are both routed to the doorlock actuators and are connected to either end
of the actuator's motor winding
.
When the switch is pushed to one position, one of these two
wires will have 12 volts. This voltage flows through the wire to the actuator's motor winding,
and since the other wire is still
resting at ground
an electrical circuit is completed. When the
switch is pushed to the opposite position the electrical flow is
reversed
. When the correct wires
are found, they must be cut. Notice in the diagram (following page) that the driver's switch is
the primary switch and referred to as the "switch" wires. The wires that go to the secondary
switch are referred to as the "motor" wires. Even though the cut is made between the switches,
the two sides are still correctly called the "switch" and the "motor" sides, with consideration of
"Primary" and "Secondary" switch; please see the diagram.
There are
other, specialized types of power doorlock systems
which may be
encountered. Examples of these are the single wire, dual-voltage which has appeared in
some late model vehicles, vehicles which control the power doorlocking system through the
on-board data bus, and the vacuum pump types found in older Mercedes vehicles. In most
all of these cases, Omega will have an optional specialized power doorlock interface available,
in which case any needed instructions will be included with the specialized interface.

operator, and preferably where it can be seen from the exterior of the vehicle. Drill a hole in
a suitable interior panel, route the wiring harness through the hole to the control module, and
snap the Status Light in place. Plug the Status Light’s small 2-pin plug into the matching red
port on the control module. Mount the Valet Switch, using its adhesive pad, in a hidden location
which is accessible to the operator; carefully route the wires to the control module, and plug
the valet switch’s blue 2-pin plug into the control module’s blue 2-pin port.
Also included is a
holder
for the Status Light. Mount the holder, using the double-sided
adhesive tape, in a location where it can easily be seen by the driver, and preferably where
it can be seen from outside. Properly prepare the mounting surfaces to ensure good adhesion,
and then affix the completed holder.
