CONNECTING THE MAIN WIRING HARNESS TO THE MODULE

Carefully plug the main harness into the 1402 module. DO NOT plug

the harnesses into the control module until all connections have

been made. Be careful to line up the pins on the unit with the

wiring harness plug (lip up - Red wire to the right). Failure to do

this will cause severe damage to the unit and possibly to the

vehicle.

CONNECTING THE STARTER DISABLE (Part #773 Required)

Locate the cranking wire at the base of the steering column. When testing,

the cranking wire will show 12 DC only when the key is in the cranking

position. Once located, cut the wire in two. Try to crank the engine, it

should not crank. Next, mark both ends of the cranking wire. The wire

running back into the steering column, mark “Key Side”, and the wire

running toward the engine, mark “Starter Side”.

Connect the control module BLUE/BLACK wire negative (-) out when

armed to the optional starter disable relay (-) negative input.

Use a wire tie to secure the starter disable relay to a non-moving part

under the dash.

DETERMINING YOUR VEHICLE’S DOOR PIN SWITCH TYPE

NOTE: For your alarm system’s arming feature to work, you must

connect the alarm to the door pin switch.
On some vehicles this wire might also be called a door trigger and is

usually located behind the driver’s kick panel. Some vehicles have logic

controlled dome and courtesy lights that turn on differently depending

on which vehicle door is opened. NOTE: Some vehicles such as Honda

have door switch isolation diodes on each door. These vehicles

must be wired at the wire that triggers the dome light circuit after

the diodes. If the door switch wires are difficult to reach, connect

the input wire to the dome light itself. Be sure to locate a wire

that is triggered from all your vehicle’s doors.
Touch your test light’s positive lead to a point on the fuse block that has

constant 12 volts. Use the other lead to probe the control wire. Then open

the door. If the test light turns on, your vehicle has a negative

(-) switch door pin.
Connect your test light’s negative lead to a good solid chassis ground.

Use the positive lead or other lead to probe the control wire. Then open

the door. If the test light illuminates, your vehicle has a positive (+)

switch door pin.
Use masking tape to mark the wire with its function “Dome Light” and

switching type “positive” or “negative”.
CONNECTING THE DOOR PIN SWITCH (Programmable option)

Connect the RED/BLACK wire from the module to the wire marked “Dome

Light”. (Select positive or negative according to the pin switch type when

in programming mode - refer to programming mode, page 25. NOTE:

The door inputs activate 10 seconds after arming. If the 1402 chirps three

times with the door closed, after arming the system, the wrong door

option has been selected.
FINDING THE EXISTING CAR HORN WIRE

The existing car horn wire will usually be found in a harness at the base

of the steering column. Probe for a wire which will remain neutral until

the horn is pressed. When the horn is pressed, the test light will show a

negative pulse or a ground. To be sure that this is the correct wire, simply

pulse the chassis ground to this wire. The horn should sound. Mark this

wire with its function, “Horn”.
