Black Ground Wire
BRAKE INPUT
The brake wire is located on the switch near and above the brake pedal. The correct wire will show
+12V only when the brake is pressed. Connect the BLUE WITH BLACK STRIPE from the 18-pin harness to this
wire.
PARKING LIGHTS (+12V only with parking lights on)
Turn the parking lights to the ON position. (NOT YOUR HEADLAMPS).
Probe the wire(s) coming from your headlamp control switch. Find
a wire that will show +12V only when the parking lights are ON.
Connect the BROWN wire from the 18-pin harness to this wire. If
this wire tests as a (-) negative, see diagram.
DO NOT USE THE RED WIRE, TAPE OFF.

HOOD PIN SWITCH
This feature will keep the engine from starting or shut off the engine when the hood is opened.
Locate a good chassis ground, if at all possible do not install the pin switch in the rain gutter.
Drill a 5/16 hole, insert the pin switch into the hole and tighten. Check for the hood adjustment,
there is approximately 1/4” adjustment in the pin switch. Close the hood easy, making sure that
the pin switch is not keeping the hood from closing all the way, if it does, cut off approximately
1/8” of the black plastic off of the top of the hoodpin switch and try closing the hood again.
Check to make sure that the hoodpin switch remains neutral when the hood is closed and shows ground
when the hood is open. Plug the BLACK WITH BLUE STRIPE wire from the 18-pin harness into the bottom
of the hood pin switch.
TACH INPUT (Optional)
By this time, you should have determined the way you want your vehicle to start (tach or tachless).
You should usually try TACHLESS first. NOTE: If your vehicle does not start in TACHLESS mode, and
you feel that it is not getting enough crank time see programming “Double Crank Time”, page 20
before deciding to connect the Tach wire. If you have chosen the TACHLESS start option, simply
proceed to the next step and skip the following instructions. Make sure the tach wire is taped
when not used. For TACH mode connect the BLACK WITH WHITE STRIPE wire from the 18-pin harness to
the negative side of the coil or the tach wire at the coil pack under the hood. To find the coil
pack follow the spark plug wires back to the termination point. To operate in tach mode, make sure
to program tach option, see programming tach option page 9.
FACTORY ALARM SHUT DOWN WIRE (FASD) (-)
If your vehicle is equipped with a factory alarm system (as most vehicles with a factory keyless entry
are) probe for a small gauge wire (usually found in the driver’s side kick panel) that shows (-) ground
when the door lock cylinder is turned to the unlock position using the key. This wire will usually show
a (+) positive voltage before turning the key. NOTE: Some factory disarm wires remain neutral before
you turn the key to unlock instead of +12v positive. Connect the RED WITH BLACK STRIPE wire from the
18-pin harness to this wire.
CHASSIS GROUND
Locate an easy to get to bolt or screw
located under the driver’s side of the dash and
attach the BLACK ground wire from the 18-pin
harness securely as pictured.
DIESEL INSTALLATION ONLY
Connecting the Glow Plug or Wait to Start Wire
When installing on a diesel engine, a wire that energizes the Glow Plug (also known as the Wait to Start
Wire), must be located and identified. This wire is usually located at the instrument cluster or at the ECM
(electronic control module). This wire will, depending on the year, make and model of the vehicle, test as
a (+) positive or a (-) negative.
TO TEST FOR NEGATIVE: Clip the test light to ground, then probe the wire and turn the ignition key on. The
“Wait to Start Light” on the dash should be illuminated, the test light should also be illuminated. When the
“Wait to Start Light” on the dash goes out and the test light also goes out this is a (-) negative wire.
Connect the GREEN WITH THE BLACK STRIPE wire from the 18-pin harness to this wire.
TO TEST FOR POSITIVE: Clip the test light to ground, then probe the wire and turn the ignition key on. The
“Wait to Start Light” on the dash should be illuminated, the test light should not be illuminated. When the
“Wait to Start Light” on the dash goes out but the test light is illuminated this is a (+) positive wire.
Connect the BROWN WITH THE BLACK STRIPE wire from the 18-pin harness to this wire.
NOTE: You will need to program your unit for Diesel Start Mode. See programming on page 9.
