I am buying a Lund brand tach for my 1982 rude 35hp. Are these easy to wire? What pulse should I set it to? Is all there to it is set the pulse and one wire?? thanks
tach setting is scale 5 for omc tachs 10 pole alt<br />make sure you have a charge system on moter<br />if using an omc control single lever with key switch but part number 173632 and plug it into control<br />purple wire is power<br />black wire is ground<br />gray wire is tach signal<br />hope this helps
