Help!!! I need help with the Autometer air/fuel gauge!
 

I'm new to this forum and proud to be a FD owner... I just got my FD 2 days ago and I can't wait to mod it already.... I have a Autometer air/fuel gauge and I have trouble locating the Oxygen sensor wire at the ECU.... can anyone tell me which wire it is? or is there a website with the ECU pin outs? any help would be great!

How to Tap Into the O2 Sensor at the ECU to Install an Air/Fuel Gauge
I asked this question a couple of weeks ago and didn’t get an answer so I dug out the Shop Manual while installing an HKS FCON and looked for the oxygen sensor wire at the ECU. I wanted to tap into the O2 sensor at the ECU to install a Cyberdyne/Intellitronix air/fuel meter. The O2 sensor wire is a solid black wire on the only 16 conductor ECU connector. The ECU is located behind a plastic panel next to the passenger’s right foot. The Shop Manual calls the O2 wire 3C. When viewing the connector from the wire end and with the locking clip on top, it is the second wire from the right on the top row (it’s the only solid black wire on the connector). I put a wire tap that accepts a blade type male connector on wire 3C so I could easily remove the wire it later.
