Good morning,
I recently bought a boat and want to install a tach for monitoring my rpms. The problem is, I’m not sure where to begin. I have found some that include just a wire the wraps around a plug wire. Other units have 3 wires are hard wired in. But I can’t figure out where to run the 3rd wire I’m trying to install this on a 2018 40hp 4-stroke mercury.
I’d appreciate any info you can give me.
