if is like the LAST "as you found" diagram ( because he posted two "as you found" diagrams LOL ), you are set on the parallel path ready for higher amperage setup like I allways suggest. Just reinstall it back like it was.

How it does look the bulkhead ? some burnt spot ?

I think already have explained enough what to do with the stock red wire going through the bulkhead, but once again:

-No reason to remove it if bulkhead paths are in nice conditions. Is posible and even healthy keep it in use BUT splice both reds into one fuse link to Starter relay, the 14 gauge one

or

-Remove the blue fuse link. No reason to have it there being feeded and sourcing to nowhere on the other side, having unnecesarilly a hot spot hanging around without any use.


get a 80 or even better a 100 amps alt and your car will be happiest than never before
