We have no emissions where I'm at in PA either but I'm worried about my 240/SR20 swap if I ever decide to move.

I've personally never put an OBD I engine in an OBD IIa car before, so I can't tell you exactly what needs to be done, but I would recommend picking up the Helm's manuals for both your car and the car your engine is from and with the wiring diagrams in both, you should be able to figure just about anything out. Their worth having regardless but will really come in handly for that wiring conversion.
