Only problem is I can't find a plug for it in the 83 harness and I am sure I will have to do more than just plug it up to get a tach signal.

That vac pump may be from a late late 6.2 out of a GMT-400 or even a 6.5. Never was diesel + tach in squarebody. I got an alternator with an R-terminal on it for my dad's '87 to get a tach signal.
