3/B Courtesy Light Output (16 AWG) (BLACK/WHITE)

Locate the vehicle courtesy light wire.

Verification: This wire is usually the door pin switch wire. Refer to

testing procedure in 20/B to determine the correct polarity of the

courtesy light system.

Connect wire to the courtesy light wire.

IMPORTANT!

After installation, set the polarity of this circuit by moving the

fuse inside of the control module to positive (+) or negative(-).

4/B Main Power (14 AWG) (RED)

Connect the 4/B wire to the vehicle main power wire at the ignition switch.

Verification: This wire registers voltage through every position of

the ignition switch.

5/B Chassis Ground (14 AWG) (BLACK)

Connect the 5/B wire to a solid chassis ground point. Scrape

away paint from the grounding point to ensure a good connection.

Note: Do not ground the 5B wire with any other vehicle components.

6/B Starter Input Key Side (14 AWG) (VIOLET/RED)

8/B Starter Output Motor Side (14 AWG) (VIOLET)

Locate the vehicle starter wire.

Verification: This wire registers voltage only when the key is turned

to the START position.

Cut the vehicle starter wire in half.

Verification after starter wire is cut:

• KEY SIDE of starter wire registers voltage when the key is turned

to the START position.

• MOTOR SIDE of starter wire registers no voltage.

Connect the 6/B wire to the KEY SIDE of the vehicle starter wire at

the ignition switch harness.

Connect the 8/B wire to the MOTOR SIDE of the vehicle starter wire.

7/B Ignition 1 Input/Output (14 AWG+) (PINK)

Connect 7/B wire to the vehicle ignition wire at the ignition switch.

Verification: This wire registers voltage when the key is turned to

the ON (or RUN) position. The voltage does not drop out when the

key is turned to the START (or CRANK) position.

10/B Door Trigger 10K Pull-up Resistor (20 AWG) (YEL/WHT)

For vehicles with a door input battery saver mode (i.e., Ford Windstar,

Lincoln LS, Cadillac DeVille):

Connect the 16/A wire to a fused constant 12 volt source.

Note: An internal 10k resistor will prevent the door input from going

into battery saver mode to prevent alarm falsing.
