Wiring harness plug. No idea where it goes.

As the title says.

I can't seem to remember, nor find, a place where this 4 pin connector would plug into. Any help appreciated.

Nevermind, I found it. I will post the picture of where it goes a little later if you all are still interested. Otherwise, delete this thread thanks for help!

Hi !
White 4 connector one is to the O2 sensor on the back of the engine.

Did your check engine light come on after reconnecting it?
