In many ways, it would be simpler if that were the case, but the Trooper/P'up shares little more than some powertrain options with the S-10/Blazer line. Different frames, bodies, etc. The later Hombre was a rebadged S-10, but that's about it.

I've since passed on my shop manual, but what I recall is that the Trooper and P'up were screwed together pretty much the same across years from the firewall forward, at least. Wiring information for the truck should translate, although I won't swear that component location will be the absolute same between the two.

Hang tight, and I'm sure some of our resident diesel burners will be able to chime on the subject.
