[arnoldg]

i need to replace my ignition switch but having trouble locating part number. Can any shed some light on this matter?
the switch has 10 wires coming out of it.

Serial number OD199434
mercury 175XRI 1994

Does any one know what the difference is between a 5 wire switch and 10 wire switch?

Thanks in advance
