Icon5 Intake Manifold Question OBD2 on OBD1 Engine

Sorry if this has been answered before. I looked around and could not find a definite answer.

I was given an intake manifold complete with throttle body. I was told it was off an OBD2 engine. I had and OBD1 H22A. I can see a few differences like there are 3 vacuum fittings on the top back of the intake next to the throttle body where mine only has 2 fittings. Also on the end opposite the throttle body there are no vacuum fittings and mine has 2 fittings there. On the throttle body itself I have 2 cables and this one there is only a place for 1 cable. I need only the throttle body but was wondering if I could use the entire set up? I figured I could clean it up inside and out and have basically a new intake. If this is possible what about the vacuum lines what routing would I use? I also have seen some intake spacers around. Is this worth doing while am at it?

Ok why are you switching intake mani's in the first place.

Just swap the throttle bodys everything else is the same
Someone took the map sensor off the obd2 mani.
but you don't need it cause your obd1

Re: Intake Manifold Question OBD2 on OBD1 Engine

I was going to change the manifold becuase I keep getting an EGR code. I have replaced everything in the EGR system short of the intake. I can not clean the egr ports on the intake as it seems they have by covered with something like maybe JB Weld. I was thinking of maybe just using the Throttle Body but was wondering about the vacuum line on it. I believe it goes to the Canister or Canister Purge Valve. I am not with my car now so I can't see for sure which it goes to. Also there is only a place on that throttle body for one cable. Mine has two cables. I assume one is the Cruise but can't remember for sure taht right now either.
