If the pic is the wrong thing, then ALLDATADIY is wrong...
In the official MB schematic of the CCU wiring, item M13 is labeled "Coolant Circulation Pump"
The wires on the pump should be:
Pin1=BKPKVT (BLACK/PINK/VIOLET?) (Hot wire/power source)
Pin2=BNGN (BROWN/GREEN?) (Gets grounded by the CCU to enggage)
This hot wire/power source comes from pin 20 of the CCU which also provides power to the "Y19 Monovalve", the "Y11 Switchover valve block" and the "B10/4 in-car temperature sensor fan."
The monovalve will have the same BKPKVT wire on pin 1, but pin 2 will be BNRD, so I presume that would be Brown/Red.
What are your wire colors? Perhaps that will confirm what you are seeing!
