Gang,

Need your eyes please.

Tell me if you guys are seeing the same colors as my color perception ?
My side : Camera white balance is good, screen color calibration is decent.






My colors perception. MB WIS wiring diagram definition of PINK and YELLOW seems wrong to me, as per real physical wire itself. I know some are aging due to heat.



The connector wire colors in discussion is the X26 no 2 connector




Thanks.....

They have color blind people on staff blending low toxicity pigments

It's hard to guess what these wires color may have been except for blk brn

I think different supplier of MB has different color blending.
This is X26 no 4, see pin 4 how different one connector's blue to the other







Since the wire harness is disconnected now, I might as well logged the colors.
This X26 #4 is good it exist, this is an intermediate connector to experiment to : by-pass the 2 stage oil control valve. So no need me digging at the final connector besides the crankshaft pulley.
So no need aftercooler removal. Yeah !!!!

=======================
Pin 4 , LIN for alternator

Pin 7 & 8, Y130 Engine Oil Pump Valve ( 2 stage control ). Pin 7 is power source, circuit 87M2e

Pin 9 & 10, Y101/2 Bank 1 ( RIGHT SIDE ) Turbo Bypass Valve. Pin 9 is power source, circuit 87M2e

Pin 13, S43 Oil Level Switch
=========================








X26 #4 location is here :





There is another X26 #1 which has 3 wires I do not know yet its function based on ECM diagram.
Pin 1, 2 and 8 ..... The unknown. Maybe some options my car does not have.
