so i have a 95 sunfire with a obd-2 port and was told that it is a obd-2 port with a obd-1 haness is that true? when i hook up a obd-2 scan tool it says link error, any way i have got the innovate motorsports wideband and need a true obd-2 system to data log, so if i was to swap engine harnesses and ecus will the motor still run right, and what besides a 2nd o2 sensor is the difference?

thanks in advance
jason
