Hello, I need your help. I am trying to incorporate this “12 Volt Timer Relay, DROK 0.1s to 999min 50mA Automotive. “I am trying to connect the timer relay to the horn and an alarm siren to my truck, so when the truck is on, the horn works normally, and when off, the alarm siren kicks in. I will put a diagram of what I’m trying to do if someone can help me.

Heres the link to both diagrams working and not working Drok Diagrams and Relays
