Based on stealth316 ECM page, he listed the 98-99 DOHC and TURBO models with the same pins layout. There are a hand full of pins that are not used by the DOHC NA but are used for the Turbo Model.
Pin 41: Waste gate solenoid
Pin 48: Fuel pressure regulator
Pin 55: Turbo Fuel Pump Relay 2
Pin 75: Active Exhaust
Pin 77: Turbo Meter(Boost Gauge)
Most cars get rid of things like these. My question is what is special about your harness that boomslang or any other place that makes a conversion harness pertaining to a 3s DOHC ECU? Have guys explored the DOHC NA ECU as the most ideal ECU to use if available for Turbo models?
