Ignition detection solution

I have a RUT956 and I need it to stay on for 1 hour after the ignition switch is off.
I found this Ignition detection solution - Teltonika Networks Wiki but it does not specify what hardware do I need.

This is what I think I need.

POWER CABLE WITH 4-WAY SCREW TERMINAL PR2FK20M
Diode 1N4001

Would this relay work?

Hi,

Yes, a relay like this should work fine, just like any standard relay. Just make sure it’s a 12V relay if your vehicle operates on a 12V system, or a 24V relay if it operates on a 24V system.

Don’t forget a fuse.

Best regards,
