find out the year and look up top here in the stickies to see if they have a diagram, follow the wires from the back of charge receptical depending on year one of those wires should go to the battery right behind it along with a wire from the keyswitch and a few others should be positive terminal........the other wire from the receptical should run to pass side of cart front battery neg. term and there will be several other wires with it also, this is for a resistor cart with the F&R lever down by your leg.................if your battery setup is 2 in the front and 1 behind it on both sides than the wires from the charge receptical are mounted as i said..................the short wire to the battery closest to it ( pos ) and the neg wire over to the other front battery........................................... .
