The door lock / unlock outputs are designed to control several different types of systems which may require additional parts. Please review the wire and location chart to see which type of door lock system is in your vehicle. The most common types are shown in the diagrams below.

Negative Switching and Negative Switching with 2-step unlock feature:

All Door Lock and Unlock: Locate the lock / unlock wire at the vehicle’s lock / unlock switch.

Verification: These wires will register ground when the Lock and Unlock switches are activated.

Driver’s Door Unlock: Locate the unlock motor wire directly from the actuator inside the driver’s door.

Verification: This wire will rest at ground and register positive voltage when the driver’s door is unlocked.

Connect the GREEN and BLUE or BLUE/GREEN wires shown in diagram 6 below.

Note: When adding the 2 step unlock feature the BLUE/GREEN 2nd door unlock wire will be used to unlock all vehicle doors on the second press of unlock. An additional SPDT relay (not supplied) (Code Alarm part HDRLY) is required. Connect the relay as shown in diagram 7 to unlock the driver’s door on the first press of unlock.
