Worked like a charm. I installed an electronic ignition on a 72 Moto Guzzi El Dorado. Had to get a new tach in hopes of picking up the ignition signal. Bought a motogadget tach - no luck. Turns out you also need the ignition sensor. Why Motogadget doesn’t sell these with the tach is beyond me, but it was just what I needed. Tach works fine now.
I used this on my 1979 CX 500 so I could add an electric tach. Easy installation and worked great. Looks clean and works!!
