Dean, what yr is that fuse box for?

I have relays for the H4 headlights that draw their power from their own fuse on the fuse block.

Why? It would be better to put headlamps on a circuit breaker anyways.

Do y'all suppose I could use the little fuse (stock 3A) for domelight, console light, and reverse lights instead of attempting to use a bigger fuse for a radio?

All of that will draw to much and blow the fuse. Do you plan on having any dash lights? You can get higher amp fuses, try here http://www.digi-key.com

Dean and Elree, thanks for the explanation on the fuse box's.

I would still put them on a breaker, it would be no fun to try and change that fuse on the side of the road in the dark, plus it would give you another space in your fuse box.

I may reconsider the headlights infavor of a self-resetting breaker. Where can I get one of these?

You can get them at some auto part stores. Jegs has some too. Heres some from Americanautowire. They come in several styles
