I was given this 1990 D150, I've been working on it as it sits in another state while I go to school. I've got her running again and trying to get her to pass smog in Nevada, and once done I want to start restoring some of the failed parts, rebuild/replace the wiring harness because of some electrical issues.

Has anyone done something of this nature before?

It has the 5.9L V8 in her and was converted to be carburated, other than that I have to go physically verify what else is going on.
I've change the engine oil, rear brakes, a couple of fuses, new fuel lines and a new fuel pump.
