Tachometer for tuning, drifting, and motorsport. We have several types of tachometers that are universal and can be used in all types of cars. Mounting the rev counter is very easy, it must have a kl15 / ignition plus and a ground wire. And a cable must be mounted on the car's ignition coil or from the engine control. There is also a tachometer for diesel, which comes with easy to follow installation instructions.
