From a crankshaft speed/position sensor.
As far as what tachs will work: buy a tach that has what is called an "inductive" pickup. this is a clip that you put around a spark plug wire, it will give your tach the signal it needs from the engine. the rest of the basic instructions, even though they wont be for your exact car, will be in the package with the tach.

The tach signal comes out of the pcm. The pcm watches the crankshaft position sensor to calculate engine speed. The crankshaft position sensor is behind the starter.
theirs a green wire by distributer that is for the tach
Remote starters can use the AC signal from the alternator as an alternate signal which is not produced until the engine is running. On most cars if you access the PROPER wire for the tach it almost always is strong enough. Double check your wiring diagrams and make sure you are accessing the correct wire from the coil pak or ignition coils.
green wire on aftermarket tachs are the signal wire i belive
Tach signal wire is located at the PCM near the connector. Use the manual should there be need for help in locating it.

The tach signal wire for a 2005 Hyundai Tiburon is typically located at the engine's ignition system. You'll find it on the ignition coil, where it sends a signal to the engine control unit (ECU). It's usually a green wire, but it's best to consult a wiring diagram for precise identification. Always ensure the vehicle is turned off and disconnected from the battery before working on electrical components.
Tach is driven by a motor signal, speedo is from the trans the sensor is bad on the transmission
All of the ones that I have worked on have the tach pickup made into the alternator, believe it or not. There are two different alternators that can go on this engine and they look the same from the outside and use all the same wires. They are delco-remy. I'll get you the part numbers.
