Orange Wire: Ground When Armed Output
This wire provides a 300 mA ground output when the alarm circuit is armed to control the starter inhibit
relay. Connect the Orange wire to terminal #86 (orange wire) of the relay provided. Connect terminal #85
(red wire) of the relay to an ignition wire in the vehicle that is +12 volts when the ignition switch is turned to
the on and start positions and off when the key is off. Locate and cut the low current start solenoid wire
found at the vehicles ignition switch harness. This wire will have + 12 volts when the ignition key is moved
to the start (crank) position and will have 0 volts in all other key positions. Connect one side of the cut wire
to terminal #87a ( Black wire) of the relay. Connect the other side of the cut wire to terminal #30 (White/
Black wire) of the relay. See below for detail of wiring, also see Yellow Start wire detail for connection to
vehicle considerations.

Failure to do so may result in personal injury or property damage. See detail of wiring in the following
diagram. This wire may also be used if the vehicle brake light circuit switches ground to the brake
lights. An isolation diode must be used for ground switched brake light circuits and must be connected
to the output of the brake switch.
