Can someone please take a picture of their high-pressure switch for me to see? The plug on this one was replaced, and I have reason to believe some wires were crossed

I'm 95% sure this is the catalytic converter as it's a smog era car, and there's no resonator, just a muffler

My question is, did this likely deteriorate on its own, or did the previous owner likely empty it?
