Need some help data logging wideband

[thor'svr4]

Ok so ive read a few threads on here about how I can hook up the output wire from my wideband to pin 53 on the ECU and data log the wideband readings. The problem is that I couldn’t get this to work.

From what ive read pin 53 is for EGRT which is not used on any 3S except for the CA spec models. Based on the ECU pin-out diagram from stealth 316 it looks like my ECU does have a green/black wire coming out of pin 53.

Am I reading the pin out diagram wrong? Im looking at the image as if I was looking at the ECU with the 3 mounting tabs that bolt the ECU to the center console facing down.

i tried hooking up the wideband to the green/black wire in pin 53 but the datalogger still didnt read wideband.

anyone got any pics of what wire or know the color?
