I know I have to rewire the harness at the connectors, any other issues?

shouldn't be

engines are identical [except exhaust man]
Sensors should all be the same.
I think there are 1 or 2 more wires for the 92/93.
Check the ecu pinouts I gave you.

i have a 90/91 3sgte ECU I'd sell to you cheap if you're interested. I was told it has a short in the connector for the distributor signal. Maybe you could fix it pretty easy. $50 shipped and it's yours. It's the JDM one which has a slighter more aggressive timing map. Let me know!
