Necessary parts for OBD0 to OBD1 Conversion
If I wanted to convert to OBD1 from OBD0 WITHOUT using the conversion harness, what would I need exactly other stuff listed below.
1)Complete OBD1 harness
2)OBD1 distributor
3)OBD1 ECU
4)OBD1 Injectors

You still need a conversion harness 
You can use the OBD1 engine harness. I think you can get away with using obd0 injectors, just remove the resistor box from the circuit. However you would need to change the injector plug types.
You COULD change the chassis harness, but that is a lot more time/effort/money than just getting an ecu conversion harness.

I think this guy has real cheap harness conversions for this. like a 150 shipped. Might be cheaper and deffinately would be easier than getting all that other stuff.
Just look on ebay under harnesses.
