Can someone with a 2002 5.3
Show me the connector on the harness for the up stream oxygen sensor?

I swapped my 2000 4.3 for a 5.3 2002

The stock manifolds came with the engine and the harness with the upstream o2s but i can't plug them in because i can't find the connector I have the after cats o2s plugged in but i can't find the ones for the upstream
Its flat and has 4pins idk if its behind something or what but i would like to know what i'm looking for lol

 

I'll see if I can get one for you after work if someone hasn't gotten it for you before then.

 

Thanks man
