Default 1994 WRX wiring and ECU

1994 EJ20G WRX with 5 Spd manual trans. I need a engine harness and ECU. After the engine is installed and running I will want to do some engine upgrades. So far I have not been able to find a piggyback system that is compatible with that year of ECU. After much research I prefer the piggyback system.

Does anyone have definite knowledge as what ECU I could use so I can remap the parameters and enhance the performance once upgrades are implemented. Or is it an impossibility.
