The V8 Owners Forum -

what's the difference between the normal and mini blade fuses, is it just the size? I'd like to use the mini ones as I can fit more of them in a fuse box and it'd look neater.

How do i figure what cable sizes/ratings to use on various parts of the loom, is it based on amps?

I would like to use blade fuses for my new loom but don't know what to get as yet. It's already starting to melt my head despite Marki sending me a wiring diagram

Apologies I have no knowledge of electrics!

yes its just a different size of fuse and obviously you need a different fuse box for them to fit. Cable size is calculated on amps. The link I sent you has what amps a cable of x size will safely carry on their cable page.
