My boat is a 9.8 HP Mercury and 110 is the model of the engine and the serial number is 3923760.

I cannot find a matching replacement part. I can find a part that replaces the original part number but the wires don't match up and they are not the same colors. And nobody has a schematic for the new part.

My question is where can I find a true replacement part or a schematic to tell me where each wire goes for the switch box.
