14-Pin Main Harness
Pin 1 - BLACK: Ground.
Connect to a solid chassis ground. Be sure to use a ring connector of proper size. Scrape
away the paint at the grounding point.
Pin 2 - RED: Main Power (+12v) input [3A fuse]
Connect to constant +12v. A clean source of power is essential. This connection can be
made at either the battery or at the constant power supply wire to the ignition switch. Be
sure to install a fuse near the connection. Do not remove or bypass the fuse holder
included on the wire harness.
Pin 3 - VIOLET: Ignition input (+12v) input.
Connect to a source that maintains +12v when the ignition key is in both the "on" and "start"
positions.
Pin 4 - WHITE: Door Trigger (-) input
Connect to negative door switch circuit. This circuit will show ground (-) when the door is
open.
Pin 5 - YELLOW: Door Trigger (+12v) input
Connect to positive door switch circuit. This circuit, commonly found in Ford vehicles, will
show +12v when the door is open.
Pin 6 - WHITE/brown: Hood/Trunk Trigger (-) input
Connect to negative output from hood and/or trunk switches.
Pin 7 - WHITE/violet: Optional Sensor (-) trigger input.
Connect to the negative trigger output from an optional sensor.

wire to chassis ground.
Pin 9 - WHITE/green: Door Lock (-) / Door Unlock (+)
Pin 10 - WHITE/blue: Door Unlock (-) / Door Lock (+)
These wires can be directly connected to negative and positive triggered door lock systems.
For Voltage Reversal systems and After-market actuators, add relays. For further
