When I moved my battery from under the cab
to the bed box, I used A Bigg' un for positive...(01) as I recall.
We needed to replace a couple of battery cables on the shop forklifts, as well. So, I picked up a cable crimper from Harbor Freight. Between the truck and the forklifts we needed to crimp about a dozen lugs. $ 70.00 crimper worked well enough.
