NOTES: Must go inside of the front Driver's door, the front Passenger door and the Rear Hatch to wire (3) separate Type C systems to the lock motors in each door. The wires are GRAY for lock and TAN for unlock. This will lock and unlock the two front doors and the rear hatch only. The middle doors, must be wired as a Type B system using the LT. BLUE for lock and the WHITE for unlock. The wires are located under the rear seat on the driver's side.

You can go here to purchase an interface for the door lock system that will make the installation WAY easier than placing relays for the locking system:
