Loose plug hanging near bank 1 upstream o2 sensor 2000 LX470

[5500lbs]

What might this plug into?

Nothing, if everything works. We've many wire housing blocks unused. Harness are built for many model variation world wide.

That's what I thought. But i was hoping that plugging it to something would keep the P420 code away.

I think the P420 code gets cleared when you pull into a marijuana dispensary.

Nope.

As for the unused plug...it is most likely there for a low oil level sensor used on the 105's (same as the 80 series have).
