• my car has the w terminal but i dont have the cash to buy a new cluster. can i just take a tach and hook the signal part of it up to the w terminal?

• Yes, as long as that tach is a diesel specific one. Gasser tachs run of the distributer (different signal).

• If it goes to 7K its a gasser.

• I doubt it but I don't know.
  
  Look for markings on it and type them into google

• i don't think it hurts anything to hook them up, it looks pretty funny though

• The W signal is approximately 12 times faster than a gasser tach will expect, and the waveform is different as well... let us know what you find out !
