Product Research


Overview: The Audiovox PRO-PDL-4B Power Door Lock kit contains the control module, actuators, and wiring for adding power door locks to four doors in your vehicle. The system can accept a positive or negative trigger from an alarm or keyless entry system (sold separately). The kit can also operate independently, using the action of one of the front doors (using the key or operating the door lock lever) to trigger the other doors to lock or unlock. The rear doors cannot control any of the other doors.

Installation: The kit's control module is mounted near the vehicle's fuse box to allow easy connection to 12V+ and ground wires. The remaining wires are routed through the door jambs and into the doors. The kit includes flexible rubber tubes to protect the wires as they pass through the door jambs.
