Hopefully, this should do the trick. Worked for me. Tachometer
hey thanks !! I was pretty sure i was doing it correct. I have two tachs on my 2004 750 aero shadow . I wired into the one under neath the fuel tank.ran a ground to the battery box support baracket. ran the red and blue wire to the harness under seat above battery using the solid red wire. I aid way to much compared to your price. same drag specialties tach. it looks really cool thanks again.
