Well, if the OXS is truly missing, yah.

But since the coupes and 4kq's share a harness, you will find the
*heater* wires for the OXS bundled up on the coupe, and zip tied sorta
backwards in place.  The OXS signal wire has a light tan single pin
connector thing - is that the one that is disconnected?

Also, there is a two pin connector, whitish, that is the ISV duty cycle
measurement tap.  Not supposed to be connected.

I suspect your "plug" might be the remnants of the CO sample tube
attachment.  Examine your EM more closely and report...
