Please give me a complete list of everything that needs to be changed. I have a '91 S13 with the original KA24DE in my car right now. I'm in the process of ripping it out as we speak. I have a '96 S14 KA24DE hanging in my garage waiting to be put it. But, exactly what has to be changed to make the swap complete? Is the wiring harness an OBD2, in both, the (91)S13 KA and (96)S14 KA?

All your help is appreciated.

Thanks alot,
-Jeremy.
