What is the differences between the 2nd and 3rd gen 3s ECU?

I just picked up a 3rd gen 3sgte ECU (89664-17460) and was wondering if it'll work on a 2nd gen 3s? Besides converting my 86 aw11 wiring harness to work with the engine, what other changes do I need?

I did read up on Singularity thread about "How to convert Pauls Idiots wiring guide into a gen3 guide."

Can someone verify if this is the answer I am looking for?

Read my thread about converting a Gen2 to a Gen3. It isnt just a simple thing. You need Gen3 injectors, MAT sensor, IAT sensor, Igniter, ECU, MAP sensor, and a fair amount of rewiring (compared to a Gen2).
