16. White/Black Wire – Ignition #3 – Control Harness
The WHITE/BLACK wire, is a ground output
that acts just like the Ignition 1 or Ignition 2
relay outputs (active in the "run" and "crank"
positions). This wire is a 400 mA negative
transistor output and MUST be set up to
power a relay (not included). It can be used
to power the third ignition wire at the key (necessary for most Ford vehicles).
This is the wire that can also be used to bypass a passive vehicle anti-theft
system by hooking it up to the Universal Bypass Module. See the Factory
Anti-Theft System section at the end of these instructions.
17A. Keyless Entry Wires – Accessory Harness
Yellow/Red & Yellow/Green - Door Unlock - Accessory Harness - White/
Red & White/Green - Door Lock
The YELLOW/GREEN wire is the NC (normally closed) contact of the on-
board door unlock relay. The YELLOW/RED wire is the C (common)
contact of the on-board door unlock relay.
The WHITE/GREEN wire is the NC (normally closed) contact of the on-
board door lock relay. The WHITE/RED wire is the C (common) contact of
the on-board door lock relay. Check the separate wire colors sheet to
determine which are wire the correct lock/unlock wires in your vehicle.
To select lock polarity output:
The remote starter has a 15-amp fuse inside its case to select lock polarity.
This fuse is factory set at positive. (This fuse connects the normally open
contact of the relay to +12V or ground).
If your door locks are positive, keep the fuse set for positive as it comes
from the factory. If your door locks are negative, open the unit and change
the position of the fuse to the two positions closest to the wires. If your
door locks are reverse polarity, keep the fuse set for positive and cut the
lock and unlock wires of the vehicle in half and follow the Green Sheet
Keyless Entry Notes.
Check this chart for connecting to the 3 most popular locking styles:
AutoCommand Positive
Wire Polarity
Yellow / Red Connect to car's
Unlock wire
Yellow / Green NOT USED
White / Red Connect to car's
Lock wire
White / Green NOT USED
For Single Wire Lock Systems: Connect both the lock and unlock output
wires to the single lock/unlock wire in the vehicle with the appropriate
resistor(s) in-line. Refer to the specific vehicle wiring instructions for
further guidance on the value of resistor(s) needed and the required output
polarity (+/-).
Note: most VACUUM operated door locking systems require Option 18
(Long Locks) to be set.
17B. Green/White Wire – Trunk Release – Accessory Harness
The GREEN/WHITE wire is the Trunk Release output which gives out a
transistor ground output when the unlock button is held for 4 seconds.
This is a 400 mA transistor ground output which MUST drive a relay (not
included).

Installer Note:
By changing Option 22, the installer can supply a +12 volt relay output to
power an electric trunk and a negative output to trigger a negative horn. If
Option 22 is set, the BLUE wire now acts like a +12 volt positive trunk
output and the GREEN/WHITE wire referred to in Option 22 now acts as a
negative (-) horn/siren output. This GREEN/WHITE wire is a negative
transistor output, which can be used to directly drive the negative horn wire
at the steering column.
18. Brown Wire – Accessory Pulse/Dome Light – Control
Harness
The BROWN wire is the Accessory Pulse output which gives out a momentary,
transistor ground output 10 seconds after the vehicle is remotely started.
This is important in some vehicles to control the defroster or to control the
GM R.A.P. system. This is a 400 mA transistor ground output which MUST
drive a relay (not included).
This BROWN wire can also control a relay for Dome Light activation. When
Option #20 (section 24) is changed, this BROWN wire causes the dome light
to turn on for 25 seconds every time the doors are unlocked with the transmitter.
19A. GRAY/BLACK Wire – Door Pin/Alarm Input – Accessory
Harness
The GRAY/BLACK wire is the door pin switch input. This wire tells the unit
the status of the vehicle's doors. It is very important that the remote start
unit knows when the doors are being opened and closed during the remote
start setting process. Most vehicles have negative trigger inputs (door pins
switch is grounded (-) when door is open, +12 volts when the door is
closed). Also check that this wire goes to (-) ground when ANY of the
vehicle's doors are opened. If not, try finding this wire at the dome light
itself.
If you are installing this unit into a Positive door pin switch (many FORD
vehicles are this way), you will need to program option 23, (positive door
pin) in the "Setting Program Features" section.
This input is also used for the alarm features of this unit and is "last door
arming." Anytime the vehicle is locked with the transmitter, this input
becomes active as an alarm input.
Important Note: If you want to use the keyless entry features only - with
no alarm functions - set Option 24 (no alarm) in the "Setting Program
Features" section for No Alarm mode.
19B. GRAY Wire – Alarm Input – Accessory Harness
The GRAY alarm input wire will accept any negative alarm input. The remote
starter ignores this input during the remote starting and when the remote
starter is running the vehicle, preventing false triggering.
If you are using a sensor or input that switches to (+) when triggered, you
will need to reverse the polarity with a relay before connecting to the GRAY
wire.
