A.I.R. removal

I recently purchased an '89 3/4 ton. It has the whole A.I.R. setup on it still after 256k miles and I want it gone. My '90 doesn't have it and I like it that way. My #1 concern is the ecm, what pins do I have to jump, where do I need resistors, and what can I just leave open. The more bs I can remove off this motor, the better. Any help would be welcome.

i just ran a shorter belt on mine and then pulled everything off and out black iron pipe plugs in the manifold, it's an 88. I don't think there is anything in the ecm that you need to change....not in mine anyway.....I'm guessing this is a SBC 350, right?
