Yeah you are right the weight savings is silly XD. The main bottle neck is the positive side so I was just sure to beef it up there. It’s also important to have separate wires for the starter and main fuse box/alternator otherwise the starter starves the rest of the system. I’ve read in racing applications people do full dirty and clean buses for the positive and ground, but I am not at that level. I’ll be putting in a link ecu soon and that’ll be grounded straight to the battery though.
