I am wanting to install a tachometer on my early 90s 40hp 4 cylinder 2 stoke Mariner outboard. I have a QuickSilver control that has a wiring harness to plug a tachometer harness into, but I am not sure which one to get. The guy I bought the motor from had a tachometer and harness, that was a direct plug in, tachometer only had three terminals on the back, but he did not want to part with it. Could I get a harness and use any aftermarket tachometer, the ones that have a selector on the back for "pole" setting? Is so, what pole setting do I use?
Thanks for your help.
