I have read a lot on these battery installations and not 100% confident in what I am doing. I bought a switch that can go to 1, 2, or both. I am hooking all the wires in like in the directions and the 2/0 gauge + wire from the engine is the one making me nervous. For it to fit on my switch, I need to cut the terminal off and put a 2/0 end with a 3/8 circular connector. I really don't want to cut this if I don't need to, but don't know any other way. Does anyone have any suggestions on getting around this? Also, I would rather not have to buy a big wire cutter and a crimper. Suggestions here would be appreciated.
