Where do these connectors go?
Hi, I noticed there was a harness connector that wasnt plugged into anything. It comes from behind the alternator. Anyone know where this is supposed to go? Also have a connector behind the drivers front wheel that isnt in anything? See attached pictures. I have code P0135 which is for the Primary Heated Oxygen Sensor (Primary HO2S) (Sensor 1) Heater Circuit Malfunction. This is the only code i have. Also the car does have an EGR and air pump delete. Not sure if either of these connectors are related to that. Thanks! 2003 MY.

The top picture is for the current sensor for the secondary air injection system. Since you have an air pump delete that plug can be left hanging. I might be wrong but the bottom plug could be your knock sensor plug.

Second picture should be knock sensor, since the shape of the plug matches and it has a 1 pin connector. Surprised you're not getting a P0325 code. Just fixed mine a few weeks ago.
