The negative is like you said from post to fender then down to the block. Probably can do that one from below. The positive runs along the front of the compartment then way down to netherlands to the starter. I don't know about another negative. I'll give it another look tonight. I'll just do a belly flop on the top of the fenders and then crawl underneath.
