When installing an aftermarket tachometer on a 1994 Nissan Sentra, the green wire should connect to the negative of the ignition coil...right?
Well, should I use any types of resistance or fuses for that wire or directly to the wire is safe for my car and my Tachometer???
Just follow the directions of your new tachometer.
And yes you hook up to the Negative side of the coil. Don't worry about any fuses to be installed, if it grounds out the car just stops running! :o)
