You can find a OBD2 harness from a 96 C4, but you would have to change the early Opti unit to a late model unit and add a crank sensor and a reluctor wheel. And add another set of O2s into your exhaust.

Why do you want to change to a OBD2 system?? It would be more do-able to change to a 95 PCM and the associated hardware.

Also keep in mind that the 93 is speed density and 94 up is MAF so that would have to be added as well.
