Adding a “Switched on” auxiliary fuse box?
Hey all, trying to wire up an auxiliary fuse box for some low power accessories. Fans, radio, USB ports, etc.. Currently, I have the aux fuse box wired directly to the battery. Everything is on unless the battery cables aren’t hooked up.
Obviously, that’s no good and will drain my starter batteries quickly, so I want to wire this fuse box to the ignition to be switched on only when the key is turned.
Seemingly an easy job, but there’s honestly just so much information out there and I’m looking to simplify and make it work for me.
The auxiliary fuse box is 12 circuit and 100A, so I know I need an inline fuse between the battery and the relay. Just not quite sure how to hook it to the ignition.
I’ve attached a diagram which I believe is correct for my purposes.
Terminal 86 on the fuse relay would go to the ACC circuit slot on the car fuse box with an add-a-circuit fuse tap?
Alternatively, terminal 86 could just be its own switch OR one of the “switched on” ignition wires right?
Diagrams or links to products are always appreciated! Thanks for helping out.
