WARNING:
Connecting the light blue/black to the high current circuits, will damage the control module.
Connect the light blue/black wire to terminal 86 of the AS - 9256 relay (or equivalent 30 A automotive relay), and
wire the remaining relay contacts to perform the selected function of channel 7.
Grey w/Black Trace Wire: DIESEL WAIT TO START INPUT
This wire, when connected to the wire that get + 12 volts during the glow plug preheat stage will delay the starter
output until this wire drops the 12 volts. In other words, in a Diesel vehicle with glow plug preheat circuit, when the
ignition is turned on, the vehicle will not crank until the glow plugs are hot enough to fire the atomized fuel oil when
injected into the cylinder. By connecting this wire to the glow plug + 12 volt wire, when the remote start unit
activates the ignition one output, the glow plug output also activates. The remote start sees the black/gray with
positive voltage and waits for this to go inactive( drop the 12 volts) before activating the starter motor. If this wire
is not used or you have difficulty accessing the glow plug preheat circuit, you may elect to utilize the Diesel timed
output as specified in Remote Start feature selection #9. NOTE: If Black/Gray wire is used, it will override or negate
any setting of feature #9.

WIRING THE 4 PIN AUXILIARY OUTPUT HARNESS

The auxiliary 4 pin connector provides low current outputs to control various functions in the vehicle during
different stages of the Remote Start unit's operation. Understanding these outputs and the time in which they
occur will allow you to determine if they are needed for the particular vehicle you are working on as well as how to
use them.
Lt. Green w/ Black Trace Wire: Pulsed Ground Output Before Start
The Lt. Green/Black wire will provide a 1 second 300 mA pulsed ground output 1.5 second before the remote start
unit activates as well as when the transmitter is used to disarm the system. Typical use for this output would be
to disarm a factory theft deterrent system to prevent false triggering of the factory alarm when the remote start unit
engages or when the system is used to unlock the doors.
Light Blue: Pulsed Ground Output After Start
This wire will provide a 1 second 300ma pulsed ground output after the vehicle is started under control of the
remote start unit. Typically this wire will be used to re-lock the vehicle doors if the doors unlock automatically when
the factory anti-theft system is disarmed.
Black w/ Red Trace Wire: Pulsed Ground Output After Shutdown
The Black w/ Red Trace wire will provide a 1 second 300 mA pulsed ground output after the remote start unit
shuts down. This output will occur regardless of whether the circuit times out or is manually terminated.
Typically this output will be used to re-lock the vehicle doors if the doors unlock automatically when the ignition
circuit transitions to off.
Black w/ Yellow Trace Wire: Ground Output During Start (Crank)
The Black w/ Yellow Trace wire will provide a 300 mA ground output while the starter output of the remote start unit
is active. This output can be used to activate the Crank Low/Bulb Test wire found in some GM vehicles. This wire
is also referred to as the ECM wake up wire in some vehicles.
NOTE: The outputs above are low current outputs and must be used with a relay if the circuit's requirement is
more than 300 mA.
2 Pin Transponder Control Output: (Yellow Connector)
This output is intended to allow the control of a transponder bypass interface module or transponder bypass
relay. The system also allows software selections to control the way in which this output operates.
When the unit is selected for output during the start sequence, this output will be active at the same time Ign. 3
becomes active, and will remain active until the vehicle has started. This will be used for one time read transpon-
der circuits.
When the unit is selected for transponder on, this output will become active at the same time Ign. 3 becomes
active, and will remain active all the time the unit is operational under the control of the remote start.
When the unit is selected for continuous, and the vehicle is started via the Remote Start, this output will become
active at the same time Ign. 3 becomes active and will remain active until the ignition in the vehicle goes low. This
will allow the unit to be used for continuous read transponders circuits.
2 Pin Control Switch: (Red Connector)
The Black & Black w/White Trace wires loaded in the two pin red connector enable the operation of the Remote
Start unit. When the Black w/ White Trace wire is grounded, the remote start unit is operable. When this wire is
open from ground, the remote start is disabled. Route the twin lead Black & Black w/ White Trace wires from the
control switch to the remote start unit and plug red two pin connector into the mating red two pin connector shell
of the control module.
