The backup camera doesn't use much power so your current truck fuse should be fine. With that setup, the backup camera will activate anytime you put the truck in reverse.

If you don't want to go that route, I personally like to use an add a fuse adapter.

Thanks for the insights Brent.

To add some more info for why I am doing this project: I am currently tapped into the running lights because my camera is for observation while travelling forward (simulating a rear view mirror), not backing up. The voltage is just under 12V after the long cable run and is not clean (makes the image fuzzy when braking or the turn signal is on). That is why I will use a relay triggered by the running lights to get a "clean" 12V power source.
