What wire will give me the signal for the tach on 79 35hp 2 cylinder ? I dont have a grey wire except for a grey ground wire

Big Fish, I have looked in a couple of my old evinrude books and there is no mention of a tach in either, it says to consult the tach manufacturer for the hook up diagram for any outboard. My question is this, why do you want to put a tach on such an old motor? You might try googlin tach hook up for old outboards and maybe find an answer, good luck.

Tachometer for Evinrude

Grey wire...sensor
Purple wire...12 volts <---from the key in the ON position
Black wire...Ground.

Grey is the sending unit.
Purple is 12 volts when key is ON
Black is ground

Book sez you need tach to adjust timing a couple other things,.. other wise I wouldnt bother
