If your module has positive lock outputs or flip flopping locks:
Pin 85: To (+) output from alarm
Pin 86: To (-) Ground
Pin 30: To (-) Ground
Pin 87: To WHITE/ green wire with resistor inline
Pin 87a: Not Used
If your module has negative lock outputs only:
Pin 85: To (-) output from alarm
Pin 86: To (+) 12volts fused
Pin 30: To (-) Ground
Pin 87: To WHITE/ green wire with resistor inline
Pin 87a: Not Used
You will need 2 relays obviously just wire them the same with the corresponding resistors and you should be good to go. Good luck,
Mike
