W212 om651 engine A/C wiring diagram needed?

Photo [white/red] and [brown/white] not connected due to it A/C clutch is not engaging, hope it helps.

Thank you for such a quick reply and provided wiring diagrams but mine refrigerant compressor has a 4 pin connector as shown in 1st picture attached to this post but wiring diagram shows only 2 pins.

So, 2 wires are connected as suggested in diagram to interior and engine harness connector [pin 1 and 2] and the magnetic clutch wires are not connected.
I can assume that the brown wire is just ground wire but what about red/white wire which is main for feeding the a/c clutch and engage it.

P.S. In the wiring diagram I see there is X26-C1 connection and it's changing it's pins any ideas of it as well?

So, in my case control valve in A/C compressor is connected (in my picture wire blue/green and green) #1 and 2, just A/C Clutch Magnetic Control wires are not connected.

Thank you, Boris, it seems everything is working properly, I will test it out and will give an update but for a moment A/C is working properly. :)
Just for reference please find attached photo how it looks like once you are taking out front SAM and where you could locate the needed wires for A/C refrigerant compressor clutch.
1. Take Front SAM and flip it over.
2. Locate green connector and follow the two blue/yellow wires in some point you will find it has connected together as it was shown in diagram.
3. In this point you will find that these 2 wires are connected to third wire in my case it was blue/yellow, but as I didn't have this wire in new engine harness, I connected mine red/white wire which controlling A/C compressor clutch.
4. Now I have everything working as it should, once I push A/C button in heater panel -> A/C compressor clutch is activated.

Fingers crossed that we together solved this issue.

Will give you update after some time.
Thank you one more time.
