• 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.
