Following is information relevant to the I3 version of the ECU;

I spent a few hours this morning with my dad tearing apart the harness under the dash chasing the 'M' (Violet with white Tracer) Wire.

What we found was quite interesting; The Wire quickly disappears into the bundled harness which then runs up near the Instrument Cluster panel, which then routes back down to the 'engine harness' (senders, etc.) to the under dash harness (ecu, etc.) BUT! on the harness plug side going to the ECU the wire is not terminated. check the Pictures I attached for better explaination.

After tracing the path of the wire, we decided to try measuring the Voltages present on the unused Ports at the ECU. The only Pins that we found to have Voltage was on plug A23(4.895V), and B17 (4.980V). If you look at the hand drawn diagram, you will see what my measurements gleened.

I suspect that the 'M' wire must have originally been connected to the A23 pin at the ECU because of how close the relationship with 'diagnostics' is to the adjacent pins. what do you guys think?

More;

On my ECU (F1-023A), the O2 Sensor isn't used, and the A8 pin on the ECU harness isn't wired. So if you're right about it being the AFR adjuster, then where is the data communication port? lol

Yes, no. 23 is the CO Adjuster. here is the sheet describing the diagram;

I figure that if my car doesn't have an O2 Sensor, then that is why there would be the CO Adjuster. I'd like to know where the ALDL interface originated at the ECU.confuse
