Features

Overview: The door lock relay module (451M) will interface with most electric power door lock systems drawing 30 amps or less; both relay-controlled and direct-wired reversing-polarity types. It can also drive aftermarket door lock actuators, which must be added in the driver's door of select vehicles. In addition, it can directly operate post-1985 Mercedes-Benz and Audi vacuum-driven systems if driven by a system with selectable-duration pulses (three-second minimum required). The 451M is compatible with the following types of common door lock circuits.

  • Type A: Three-wire (+) 12V pulse controlling factory lock relays
  • Type B: Three-wire (-) ground pulse controlling factory lock relays
  • Type C: Directly-wired (no factory relays) reversing-polarity switches
  • Type D: Aftermarket-actuator-driven systems. These include slave systems without an actuator in the driver's door, but with factory actuators in all the other doors; since these can be controlled with the installation of an aftermarket actuator.
  • Type E: Electrically-activated vacuum systems (Mercedes-Benz and Audi 1985 and newer). This requires special programming of the system.

Resistor Pack: The 451M comes supplied with a 27 resistor multi-pack to interface with various vehicle door locking systems.

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
