Only other similar change as far as swapping was when they moved the EVAP charcoal canister from up by the radiator to back near filler tube IIR around '98.

You can drill and tap the EGR port in the head - 16mm x 1.5. The EGR tube itself is the same between 2.2 and 2.5, and then you just need a 2.2 manifold w/EGR. By this method you can run any 2.2 long block from 90 to 98 without any check engine lights.
I've done somewhere in the neighborhood of 25 or 30 swaps and I've never had a CEL that couldn't be solved.
One thing you run into from time to time is a CEL generated due to incorrect EVAP purge flow. Usually when going from an older 2.5 to a newer 2.2 or vice-versa. The key here is that the purge system must match what the ECU is expecting and the MAP sensor solenoid vent must be plumbed for what the ECU wants - which is either a dump straight to atmosphere with a cap on the vent port or it has to be tee'd back into the purge line between the purge solenoid and the manifold. The ECU actually looks for a change in MAP sensor readings when it operates the purge solenoid on some ECU's and if you don't plumb this correctly you will pull your hair out chasing the P0441 "purge system incorrect flow" code.

There is AT/MT tranmssion ID pin, which tells the ECU if a TCU/TCM is connected....but no wiring changes are needed when doing the swap.
