Step 3: 5-Pin Power Harness Installation

The power harness contains 3 wires and two vacant sockets. Follow the wiring recommendations
enclosed for each wire.
Power Harness
First Vacant Socket: 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)
Black Wire: (Main Ground Input) Connect the black wire directly to the frame of the vehicle.
Remove any grease or dirt that might prevent a good connection.
Yellow Wire: (Switched +12 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 indicate +12 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.
Red Wire: (Main Power Input) Connect the red wire directly to the (+) battery post.
