• GRAY WIRE - Auxiliary 1 output (+/–)
15A relay. Connect to an optional feature
such as trunk release, etc.
• WHITE WIRE - Parking Light output (+/-)
10A relay. Connect to the vehicle’s parking
light wire. If the vehicle’s parking light circuit
exceeds 10 amps a relay is required. For
vehicle’s with independent left and right
parking light circuits, the parking light wires
must be connected using diodes to keep the
circuits separate.
NOTE: Do not connect the WHITE wire to
the vehicle’s headlight circuit.
• RED WIRE - +12V Battery input. Connect
the red fused wire on the main harness to a
co12V source. This source wire
should be at least 20 amp supply.
• BLACK/WHITE WIRE - Dome Light
output (+/–) 15A relay. Connect to the wire
that activates the vehicle’s dome light, usually
the door pin switch wire. NOTE: The dome
light output is usually connected to the same
wire used for the door trigger input (See
GREEN and VIOLET door trigger wires).
• BLUE/WHITE WIRE - Passenger Unlock
output (-) 500mA. Connect to an optional
relay to unlock the passenger doors when
configured for Driver Priority Unlocking.
• WHITE/RED WIRE - Auxiliary 2 output (-
) 500mA. Connect to a relay or module for
an optional feature such as power window
roll-up, etc.This output may be programmed
for momentary, timed, or latched operation.
• VIOLET WIRE - Positive door trigger (+).
Connect to the door switch circuit wire that
shows +12V when the door is open. This
type of door circuit is usually found on Ford
vehicles.
• GREEN WIRE - Negative door trigger (-).
Connect to the door switch circuit wire that
shows ground when the door is open.

• BLUE WIRE - Trunk/Hood trigger (-).
Connect the Blue wire to the trunk and/or
optional hood pin switches.The switch must
provide a ground output when opened.

6-Pin Door Lock Connector

Plug-in connector for door lock harness.
• WHITE WIRE - Lock relay N/C (87a).
• GREEN WIRE - Lock relay Common (30).
• BLUE WIRE - Unlock relay Common (30).
• BROWN WIRE - Unlock relay N/C (87a).
• VIOLET/BLACK WIRE - Lock relay N/O

(87).

• VIOLET WIRE - Unlock relay N/O (87).

Starter Defeat Connectors 

Using a volt/ohm meter locate the starter
wire (normally a heavier gauge wire) at the
ignition switch. This wire will show +12V
only during cranking. When this wire is cut
the vehicle will be unable to start.
Cut the BROWN starter disable wire (with
the two female connectors), and connect one
side to the vehicle’s starter wire coming from
the key switch. Connect the other BROWN
wire to the wire going to the starter.
Plug the female connectors on the BROWN
wires to the .250 male spade lugs on the
module.With the BROWN wires connected
to the module, the vehicle should be able to
start.

Plug in Connectors

2-Pin Red Connector:

Plug-in connector

port for LED. Mount LED in an area where
it may be easily seen from either side of the
vehicle.

2-Pin Blue Connector:

Plug-in connector

port for valet switch. Mount switch in an area
that is easily accessible from the driver’s seat.
