Electrical problem 6 cyl All Wheel Drive Manual 120000 miles

Hey. Just bought a '92 Mitsubishi 3000GT VR-4 which is great shape except the tachometer does not work. When you start the car it is at 0 RPM and stays there. I read up a lot about it on the internet but can't seem to find a definitive answer. What is your recommendation on how should I go about fixing it?
