First Vacant Socket:
(Applies to M5 Only) The first vacant wire socket is a low current (300mA)
grounded output wire that can be used to activate the vehicle’s interior lighting system when the
security system is disarmed. An additional relay is required for proper installation. See Optional
Accessory Connection for proper wiring.
Second Vacant Socket:
See Optional Accessory Connection for proper wiring.
Red Wire:
(Main Power Input) Connect the red wire directly to the (+) battery post. For best current
sensing capability from the alarms current sensing circuit, connect the red wire to the constant
power wire coming from the interior dome light.
Black Wire:
(Main Ground Input) Connect the black wire directly to the frame of the vehicle. Use a
bolt and nut to secure the wire. Scrape away any grease or paint that might prevent a good
connection.
Yellow Wire:
(Sw12 Volts From the Ignition Switch) Connect the yellow wire to a +12 volt
wire that is switched on and off by the ignition key. The correct wire will in12 volts when
the ignition key is in the “ON” and “START” positions. Do not connect the yellow wire to the “acc”
wire coming from the ignition switch.
