5 Wire Reversal Rest At Ground Systems
differ from the Negative and
Positive Pulse systems as there are no relays or doorlock control unit. In this type
of system, the switches themselves supply the positive voltage directly to the
doorlock actuators, and, more importantly, provide the return ground path. The
important thing to remember is the wires in this system rest at ground, which means
that the wires must be "opened", or cut, to make the connections.
Examine the wires on the back of the switch. Normally five wires will be found-
one will be constant 12 volts positive, regardless of the switch's position; two wires
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".
The two later 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.
Once determined, the correct wires must be cut. Notice in the following diagram
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 "Second-
ary" switch.

Green/Violet Wire - (Dome Light Output; Programmable for
Lock, Ignition, or Accessory):
The Green/Violet wire is defaulted for
domelight supervision, which illuminates the interior lights of the vehicle upon
disarming. It has a 250mA maximum current output.
CONNECTION: The proper vehicle wire to connect the Green/Violet wire to,
the dome light activation wire, will be any of the door pin switch circuits that turns
the dome light on. The correct wire will change polarity as the door is opened and
closed. If the vehicle uses a Negative switching domelight system, the activation
wire will have no voltage present and show chassis ground when a door is opened,
and up to 12 volts when the doors are closed. The correct wire will show this
change when any of the doors are opened. If it is a Positive switching system, the
above is reversed. If the vehicle has delay domelights, take this into account when
testing. Since the Blue/Black wire provides up to 250mA of current, it can typi-
cally be connected to a pin switch circuit that is triggering a relay or lighting
control module. IT CANNOT BE CONNECTED DIRECTLY TO THE
INTERIOR LIGHTS. If the door pin switch directly feeds the light, an optional
relay is required. In this case, or if the circuit is positive switching, use the follow-
ing relay diagram.
