receptacle help


i have a 94 club car 36 volt i just bought for cheap. batteries are shot i think. but the receptacle was off of the cart when i bought it and i dont know the wiring enough to know where what wire goes where. also i see a burnt fuse that was there on the cart and i dont know where that fuse was from. from what i can assume i think it goes on the receptacle. dont know for sure. any help with wiring will be appreciated.

also , as far as the batteries, will pouring new acid in them do any good?
