Just bumping this again... I bought the 1986 Fiero Service Manual, and spent the weekend (while I was in Miami) reviewing and comparing both service manuals for the 85 and the 86. I intend to put together a wiring diagram for both the 85 and the 86, similarly to how I did with the Fiero's stock ignition system (below).
I think most people can read the service manual wiring diagrams, but I find it easier sometimes when there are pictures that help it make a bit more sense. So I intend to do one for both years (to compare DA6 vs V5) so it'll be easier to understand / compare for someone who wants to do the conversion. Based on what I read so far, Ogre is correct in that both ECMs control the A/C in the same way... (in that it disables A/C when you're flooring it). I guess I never needed to mash the A/C off button every time I was getting ready to race someone when I was 19. Haha...

I'm going to muddy the waters just a bit. I hope someone will correct me, if I have mis-spoken.
I was under the impression that the 86 Duke used the DA6/HR6 compressor. I was thinking that the only V5 Dukes were the 87 and 88. (Probably because of all the other changes made to the 87-88 Duke.)
The second design DA6 was the HR6. Became standard on V6 Fieros prior to 88 MY. I can't speak to the material composition, but the HR6 was designed to accommodate R134 without damage. The DA6 was not. (My 4.9 also uses an HR6 compressor.)

So from what I know, the V6s use the DA6 / HR6 for all 4 years, 85-88.
But the 84-85 Iron Duke used the DA6, and switched to the V5 early on in the 1986 Production year.
When you look on Rock Auto, they offer both for the L4... but mostly V5s. The Service Manual only mentions the V5 for the L4s, so they likely switched it over really early in the production year.

Fair enough. 
I stand corrected. That being the case, you ought to be able to find a later set of lines for yours, so that you don't have to have custom lines built.

Yeah, I think that's the last thing I need. I need to take a look, but if there are any interim connections, all I'll need to do is replace the ones coming directly off the compressor to the hard lines.
