I need a picture of the driver side rear o2 sensor connectors. I need to know what wires go from the harness to the o2 sensor connector. For ex. O2 Senor has black grey two whites harness from truck has grey red etc.

 

Do you really expect to get any useful replies without telling us what truck you're working on? Fill in your profile so the truck's details show with every post. You can omit "F150" and "19.." or "20.." since we assume that. But put the 2-digit year, engine size, transmission model, trim level, cab/bed configuration & wheelbase, transfer case model (if 4WD), gear ratio, tire size, miles (or KMs), mods, maintenance, damage, repairs, etc. If you run out of room, put it in a signature. If you don't know all the truck's details, read this caption & follow the links in it:



If there are any terms you don't understand, read this: Automotive Terms & Abbreviations

Uploading pics of your truck would also help. This forum supports pics, but it's easier to embed them in your posts if you follow the instructions at this link:
