Does the starter relay 12v battery post need 12v?

Thanks all.

I'll try removing the all the 12v from the stud and see if it still spins. I've already pulled wads of wire out of this rig... and it still looks not so good.. lol.

A lot of the Painless harness is not too bad.. but some of the stuff is a real head scratcher. They did away with the bulkhead connector... good. They have a single 10ga wire attached to a 75A fuse feeding the entire fuse block? Great.. the 10ga wire is now the fuse.

Already bypassed the ammeter because who needs that headache. The entire electrical ecosystem is a loop. It either gets juice from the battery or the alternator... or both... what a mess. I'll get it where everything is fed from the battery and on a fuse of appropriate size.

^^Painless.. yes...lol. This is what the guy who installed the harness thought of it... and he is an electrical engineer by trade.
