Difference between OBD2b and OBD2a ECU. questionable SH02SG wire
Hello guys. I have looked at several ECU diagrams, and helm's manual for both obd2a and obd2b integra's and one thing I noticed is that the obd2a ECU has an extra secondary Heated 02 sensor ground wire (orange/blue wire at the ECU) on the D connector. The Obd2b ECU does not have this. What should I do with this wire.
I have a OBD2b LS and I have already repinned the harness for the obd2a ECU. Right now, I have a left over orange/blue wire that I don't know what part of the car to connect to. can someone help? Someone must have done this swap.
