Review on 🔌 iJDMTOY 10-Second Time Delay Relay Module: 5-Pin 12V 30A SPDT for Automotive Lighting by Kenneth Mills

This relay helped me. I wanted to prevent my Kenwood D710 from turning off and on again when I first start the car and this relay helped. Even with my radio connected directly to the battery, my Toyota's battery is small enough to have enough voltage drop at startup to cycle the radio off and on again. With this relay connected to the ignition switch circuit, when I push the start button the car starts and after a delay my radio turns on with clean 12V DC. Good.
