Welcome to the whacky world of the MB engine.
And you missed one! There are _three_, not two!
The MB engine has three single-pole water temperature senders - all of
them part # 049 919 501.
The blue wire goes to G62 - which is mounted forward of #1 plug under
the hydraulic pump bracket. It's connected to the ECU.
The green/brown (I know) is the idle stabiliser temperature sensor.
The blue/brown wire (back of cylinder head) is the temperature display.
