im guessing this engine is odbII because of all the emissions crap, and you have a 3 wire o2 sensor, where as my odbI ka had a single wire o2 sensor.

Incorrect. Please don't spread misinformation. Blue sockets are used on S13s, white sockets on S14s, it has nothing to do with OBD.
For the coil, all S13s use an external coil, S14s use an internal coil. Again, nothing to do with OBD. Nothing.
Finally, late 95 autos used a 3wire O2 sensor but were still OBD-I, as all 95 models are OBD-I. So again you're incorrect.

See above, that is not the only determining factor. However you're correct that the engine is OBD-II due to the EVAP purge valve solenoid and plug on the front of the intake for the EVAP purge valve.

There is no such thing as an 1988 S13. They began production in 1989. It does not matter what engine, ECU, or harness you have, as long as it meets 1989 DOT/EPA mandates (it dies, it's newer) and it runs/drives fine, you're ok. Whoever put the engine in got it from a 96+ up car and didn't swap the intake manifold I assume, so you have extra stuff not connected. You don't need any of it, especially trying to pass inspection. Your car has to pass for a 1989, nothing newer.
