I have a nine pin key switch from a Honda 4518 riding mower and coming out of the back of the switch are 5 wires, black , white , black/red , black/white , black/ yellow . The white wire is connected to 9 , the black/ white wire is connected to 8 , the black/ yellow wire is connected to 6 , the black/ red wire is connected to 7 , the black wire is connected to 5 but there is a R by 5 also there is a -1 on the back of the switch somebody unhooked the wires from the switch and tore out the wires I'm replacing the wires and need to know witch one is positive, witch one is run , which one is start and so on
