Relay Harness Wiring Instructions
H3/A BLACK/WHITE input to on-board interior light illumination relay #87
This wire determines what the output polarity of H1/4 will be. If the door pin circuit is negative,
connect to chassis ground. If the door circuit is positive, connect to a fused 12V source.
H3/B – H3/G power door lock wires
The system has door lock relays on-board, and can directly interface with most electric power door
lock systems drawing 30 amps or less.

Immobilizer Wiring Guide
The starter immobilizer harness can be installed as a normally open or normally closed circuit by
connecting the desired side of the three-wire immobilizer. Locate the starter wire, then cut it and
make connections as described in the following diagram. Connect wire C to the end of the wire that
is still connected to the ignition switch; connect A or B wire to the end of the wire that continues
to the vehicle’s starter circuit.
