Thanks for all the answers guys. I looked for the better part of an hour last night and I couldn't find anything in CO for an "emissions referee" but for anyone that searches this in the future here's what I've learned so far:
1) Air injection needs to go to the cat, NOT the manifolds, regardless of what hardware is present
2) None of the emissions stations in CO are actually run by the state, the ones I thought were are run by Envirotest which is the only private company allowed by the state to test 1982 and newer vehicles.
3) The 18 "independent test and repair" emissions stations are a racket, they will fail you and try to milk as much of the $715 dollars in repairs you need to qualify for a waiver out of you as they can.
So, I found all that on the test stations while trying to find out where an emissions referee might be, but I'm not sure it's a separate thing from Envirotest. The closest thing I could find was on Envirotest "about" page saying they provide referee services to California and Alaska, but nothing for CO.

So, it seems gas cap, catalytic converter and presence of a spinning AIR pump are the key to passing (past the actual emissions part of the emissions test). It'll be a while before it's all together and ready to test but once I do, I'll report back with any discoveries.
