RV Repair: cardinal 5th wheel battery wire hookup, cardinal 5th wheel, support legs

Question
bought an older cardinal [1991] 5th wheel and battery was gone. has one black wire,one white wire and one red wire,red and white wires connect to the switch that raises the front support legs,where do they connect on the battery?

Answer
Mike it sounds to me like the red wire should go to the positive side and the white goes to the negative side. In coaches the white wire is almost always in fact I have only seen 1 that was white that didn't go to the negative. To be sure look and see if the red wire goes to the middle of the switch. If so then the way I am telling you is the right way. Thanks, Bill
