Review on 🔒 Enhance Your Security with the 451M Dooor Lock Relay Module by Essentials - Easy Installation by Mark Young

This module was chosen over a two separate relay implementation for its simplicity and size. This module fits perfectly into my Crown Victoria Police Interceptor (CVPI) passenger door handle which interfaces with the door lock/unlock buttons. It includes a two-wire keyless remote cable. I routed this wire through the trunk door wire where I installed the controller under the glove box. The connector on this module connects directly to my controller (Scytek A20).
