I don't have the EFI harness on any fuse so I need to get that fixed - is it only the power wire that needs to be fused that goes to the starter relay to draw its power? If so, what size fuse should I use? Would you suggest a blade style in-line fuse?

I'm confused on how to determine what size fuse to use for the gauge of wire..

i just used the inline fuses from a 87-93 fox. They have the proper sizing and usually the same color coding if you used a factory harness. Wire gauge from what i have been seeing is 16gauge for always hots, according to the wiring diagram i have.

I'm sure someone will chime in on the specs for the fuses.

Looks like I have a 10gauge wire for power going to the starter relay + connection. I'm going to have to go to the parts store to get an inline fuse since I don't have time to go out to the salvage yard. How do I know which blade fuse to get though? (for amps, etc.)
