If it can be set for 6 pulses (6P) it will work.

This tach has no [ set ] method .Other than the light connections there are just two spades for push on connectors but no indication as to which each is for.I am guessing one is 12v and other is pulse , it appears it would be a case ground.would like to know what this tach can be used for if not for my 70 hp 1983 Merc.This OMC tach no 291274 says VDO at bottom of face does anyone know what engines it was used for.
