The wires that go bad on the lower harness are for the oil pressure and quantity gauges. I have never heard of the large starter wire in that harness going bad.

Have you tried hooking up a charger to the battery to supplement it during starts, just to rule out a situation where there is current but it just isn't quite enough to turn the starter?
