NOTE: This wire must be connected to the vehicle side of the starter cut relay (when used). For the
electrical neutral switch configuration, this connection must be made between the starter inhibit relay
(when used) and the neutral safety switch as shown in the following diagram.
Failure to connect this wire to the ignition switch side of the neutral safety switch can result in personal
injury and property damage. SEE NEUTRAL START SAFETY TEST FOR FURTHER DETAILS.

Red wire – +12V Power Input –
Remove the two 20A fuses prior to connecting these wires and do not replace them until the satellite has
been plugged into the control module. These wires are the source of current for all the circuits the relay
satellite will energize. They must be connected to a high current source. Since the factory supplies (+) 12V
to the key switch that is used to operate the motor, it is recommended that these wires be connected
there.
Note: If the factory supplies two separate (+) 12V feeds to the ignition switch, connect one RED wire of the
satellite to each feed at the switch.
Yellow wire – Ignition Output –
Connect the YELLOW wire to the ignition wire from the ignition switch. The ignition wire should receive "12
volts" when the ignition key is in the "ON" or "RUN" and "START" or "CRANK" position. When the ignition
is turned "OFF", the ignition wire should receive "0" voltage. The YELLOW wire must be connected.
Pink wire – Ignition 2 Output
Some vehicles have [2] ignition wires that must be power. Connect the PINK wire to the ignition 2 wire
from the ignition switch. The ignition wire should receive "12 volts" when the ignition key is in the "ON" or
"RUN" and "START" or "CRANK" position. When the ignition is turned "OFF", the ignition wire should
receive "0" voltage. If the PINK wire is not used, cap the end of the wire.
Brown wire – Accessory Output (Heater /ACC Output) –
Connect the BROWN wire to the accessory wire in the vehicle that powers the climate control system.
An accessory wire will show + 12 volts when the ignition switch is turned to the "ACCESSORY" or "ON"
and "RUN" positions, and will show 0 Volts when the key is turned to the "OFF" and "START" or "CRANK"
position. There will often be more than one accessory wire in the ignition harness. The correct accessory
wire will power the vehicle's climate control system. Some vehicle may have separate wires for the blower
motor and the air conditioning compressor. In such cases, it will be necessary to add a relay to power the
second accessory wire.
9 PIN WIRE HARNESS:
White wire – Parking Light Relay Output (10A power output) –
Connect the WHITE wire to the parking light wire coming from the headlight switch. Do not connect the
WHITE wire to the dashboard lighting dimmer switch. (Damage to the dimmer will result). The limitation of
the WHITE wire is 10 AMP max. Do not exceed this limit or damage to the alarm and parking relay will
result.
Red / White wire – Parking Light Relay Power Input –
The RED/WHITE wire is the input to the flashing parking light relay. The connection of the RED/WHITE
wire will determine the output polarity of the flashing parking light relay.
If the vehicle you are working on has +12volt switched parking light, you don't need connect this wire. This
wire already connected to +12 volt.
If the vehicle's parking light are ground switched, cut the RED/WHITE wire, connect the RED/WHITE wire
to chassis ground.
Red wire – System Power (+12V Constant) –
The RED wire supplies power to the system. Connect this wire to a constant +12 volt source.
Brown wire – Siren Drive Output –
This is the positive (+) output connection for the siren. Current capacity is 2 amps. Make connection to
the (+) red wire from the siren. Make the (-) black wire coming from the siren to a good chassis ground.
Black wire – System Ground –
This is main ground connection of the alarm module. Make this connection to a solid section of the vehicle
frame. Do not connect this wire to any existing ground wires supplied by the factory wire loom, make the
connection to the vehicle's frame directly.
Green wire – Negative Door Switch Sensing Input –
