high amp alternator?

Thanks for the info. So, for the one wire I should use the 2 gauge all the way back to the battery? I just installed a Ron Francis harness on the car. Do you think that would handle a 100 amp?

I used #4 AWG marine battery cable. It's stranded and easy to work with.

I have no idea what a Ron Francis harness is.
