when swapping my oem Honda Civic si 1999
header my o2 sensor got yanked when my header slipped out my hands and fell because of that my plug got yanked from the wire pins and got de pin I tried searches online and nothing I’ve tried so much from basic how to change your 02 sensor and wasn’t able to see the Wires etc in just looking for a b16a o2 sensor to see wich wires go to wich part of plug to re pin it

thanks man I was about to sell the whole car another question I doubt I’ll need the o2 now since I got an air fuel from aem question we’re do I wire the wires I see 4 red fire black ground I still have white and blue I heard that one is to the harness in the ecu some like that wich one is wich and also blue is that for turning the led? On the gauge if so were does that one go to

 

If you are asking how to modify an aem oxygen sensor to feed to the ecu then to the gauge, we will not be able to answer that question. You will have to call aem or search forums
