Re: Hooking up a RPM guage??
You didn't mention what motor you have..... If it's an outboard, I'd suggest getting that brand Tach and go by thier instructions. Some of them have pulse signals the tach has to read. If you have a inboard or I/O you can get one from your engine manufacturer and again, thier instructions. If you go after market, then you'd need thier instructions. Some aftermarket ones have fancy hook-ups. Basically your signal (sender) lead on the tach, will connect to the coil +.
