I am looking to add a fusebox that is wired to keyed power. I currently have a small fusebox that is always hot - its wired directly to 12V source (battery). I have some new electrical add-ons, but don't want them to have continuous access to 12V - basically, they could easily get left on when exiting the jeep and drain out the battery - so figure it should be possible to add in a second fuse box that requires key activated 12V. I have never really messed with the key ignition (its not original but from PO) or wired in a relay. I assume I would rather have the 12V run through a relay to the fusebox rather than directly through the ignition switch? Any suggestions or tips on how to make this work is greatly appreciated....thanks!
