Need a wiring schematic for wiring a tachometer on a 1999 2 cycle 100hp Mercury Outboard Motor. Have all the factory cables and tach, but don't know which wires goes on the tach. Thanks for any help.
gray lead is tach send,purple is tach 12V positive,black is tack ground and blue is for tach lights but is normally part of the hull wiring not the merc wiring.
