Check the following post, someone stated that they found some factory tachs. https://www.turbodieselregister.com/ubb//Forum2/HTML/000733.html

. . I did the calling of phone numbers that Terry Copeland gave me, searching for factory tachs. No luck... all gone.
DBF does state that an ISSPPO tach does use the factory wiring... . think that is the route I am going unless someone else has come up with a source for factory tachs.

I have autometer gauges in chrome mounting cups on my dash. They are 2 5/8 gauges, the tach reads up to 5,000 rpm. If interested e-mail me and I can tell you where there is a picture for you to look at.

On my '93, I found that the isspro directions showed me where to find the coupler under the dash (right near the steering colum) where the isspro tach plugged right into existing wiring. The truck is "tach ready", but you would not know it unless you read the isspro installation instructions.
