Ditto on the 'yes' ..
it's the red/yellow wire that is the temp gauge sensor wire. Connect
that to the screw-in single contact temp sensor.
The other wire is ground ..
you can ground it or just leave it there. I think it just goes to a
ground anyway , so grounding it won't hurt or help actually.

Save the 2WD 2.1 waterboxer connector plug and a few inches of wiring ...
if someone needs one, there's no easy way to get one.
