Making a Tach Harness 93 OMC Control

[swiss]

I am working to get a tach setup on my Jon Boat and 30hp Evinrude. I have the OMC control unit, year has been identified as 1993. Below the key I have a 3 prong female plug that after extensive reading on this site seems to be the tach feed from the engine at the control box. I have seen the aftermarket harnesses but would it seems simple to make a harness.

Does anyone know what the pin out is on this plug? For orientation purposes please look from the back of the control unit towards the bow of the boat.

Re: Making a Tach Harness 93 OMC Control

the wires that are in your harness will match the ones in your control
color wise ,the the connector that goes into your control by your key wire it in and plug it up ,if ya cant find the plug ya can splice at that connector and
do away with plug search some of my old post you will find what you are looking for,someone gave me the colors ,or you can wire from motor forward with new wire
