there is no such thing as a two wire screw-in temp sensor for a vanagon.
take your yellow/red temp sender wire and connect it to the single
contact on your screw-in temp sensor.
I think it will work just fine if you don't even connect the brown
ground wire..
I think that goes to ground anyway ..
but you can ground that brown wire .
can sell you a plastic 2WD t-stat housing if you wish, new.
the metal one is better. Obviously.
the plastic ones shrink, dissolve, and generally fail in silly ways,
eventually.
Don't overthink it.
cat converter cable ??? No wires go to the cat.
perhaps you mean oxygen sensor .
that connector is easy to identify ..
the green coax........that's 02 sensor signal feed to the ecu.
the double plug is 02 heat.
anytime the engine is running you should see 12 volts there.
