I acquired a 92 EZGO Freedom electric golf cart with no batteries. I inistalled 3 car batteries and it runs fine. However there are several wires presumably for accessories with large ring connectors that obviously go to battery terminals but aren't shown on the wiring diagrams. They are large gray, large black, large green and large white wires and a small black wire with what looks like a fuse holder in the middle. Can anybody tell me where they go, what they do and what voltage they need, or supply a wiring diagram that shows them? I'll remember you in my will.
