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

This is a fantastic item! Between the wiring diagram and some knowledge gleaned from a mechanic over the years, I was able to easily hook into my new Viper security system to now have automatic door locks. I also bought door locks here along with this relay. The wire under the plate took about 10 minutes. It took much longer to orientate and install the door operators. When from manual door locks to automatic door locks. I love that I don't have a button for them as the Viper system will automatically lock them when I'm inside and start the car and then unlock them when I turn it off.
