WUR is warm up regulator. Only the 1985 MY and older US W126 V8s have this.
CO is carbon monoxide. This is the adjustment on the CIS tower, it is a VERY fine adjustment of the flapper plate.
Did you ever drive the car with the donor motor?
The temp sensors are usually NTC. They will have say, high resistance at cold temps; low resistance at high temps. Just try another sensor.
Any vacuum leaks on the thing?
