Is your car a G63?
We have both diagrams.

Have you seen this one?

CLS is 4.4L bi-turbo and G63. I don't haver a factory ECU diagram for the E63, sorry.

Does the UCU look the same? If it does, I can 99% sure you can use the same diagram as the G63 and CLS63. I think the ECU is a small variation of the MED17.7.2

CLS63 AMG has the same engine with E63 , they both have 5,5 V8 biturbo;
Yes the ecu looks like , I hope we won't brake down the ecu or the Aquamist 😊
Thank you for the answers.

CLS 63's and G 63's ECUs are Med 17.7.2
but my cars (E63) MED 17.7.3
I think becouse of that my system doesn't work proberly ,
I need to find the exact schematic of the ECU ;

I'll be thankful if someone can find it for me 😇

As far as I know. All you need to do is wire the red and green wire directly to the fuel injector. You can try the grey harness first. Let me the result.

Thanks Richard ,
You mean , we only wire red and green wites to the fuel injector without using map sensor signal , right ?

The pump is working when I start the system with the buton on the gauge ,
I hear the sound of working pump but it doesn't inject any liquid , the pump only works. I don't know what triggers to work.

Can you confirm the engine does not use direct fuel injectors.
