Tach on 6.5's are taken off the alternator. The alt has likely gone T.U. if the tach isn't working. If you are adding one: Good luck finding one that you can set to run off an alternator. Otherwise I would suggest a used cluster with a tach already in it.

I put one in years ago. You'll grab the wire off the alt. I can't remember where I taped it.

Remote start on a 93? What kit do you have? Does it allow for glow time?

Thanks for the response.yes remomte on 93 yes glow time. Just wanting to find the under dash tach wire. I know the wire is on the alt. Im not sure if that is a useable signal i can install by setting the start time, would rather use tach so the system will control .

Back when I did mine the remote start was for a gasser. My brother made a timer that would wait for gp's to cycle. I have another remote start thats been sitting on the shelf for a few years and it is set up for a diesel, made by Bull Dog I think.
