Now I have time to fix that, will see running without check engine light and all stuff work 100% wright way.

I have pinout from WIS and ALLDATA and all info needed but pics and more info is welcome.

Thanks for rcompart info, but in which thread he talks about Kompressor wiring please?

Not sure if has written this in a thread but we will now as he is watchhing this thread. Rudy, I hope you can add some help for Karim. Our community owes a lot to him for sharing his build on the V8 thread. His success is what gave me the confidence to rip out my V6

Here attached pdf of ECU pinout from 113.990 engine: E 55 AMG Kompressor.
You can see that 1.1 pin is for supercharger clutch, is this signal wire and must wire second to ground ??

These are pdf sheet of fuel injection and ignition system from same engine.

At the pdf "E 55 AMG Komp 113.990 sheet 2.pdf" you can see that Y2/1 IS SUPERCHARGER MAGNETIC CLUTCH:
- 0.75MM BKPK (black pink) wired to ecu pin 1.1
- 0.75mm RDGN (red green) is wired to Z7/36 ---> what does it mean Z7/36 ?? is it a relay, or gnd point or fuse??? any idea?

Karim,

I'd need to see the other PDFs because there is a good chance that Z7/36 is actually a fused +12vdc supply somewhere in the engine harness or in the engine compartment. It would make sense because the relay would close to ground in the RCM to engage the clutch. If you want, you can give me a call or email me. My email is rudy@acceleratedindustries.com and my phone number is 952-681-1000.

Thanks

Wiring Kompressor RESOLVED !

I've got it!

In the front SAM module and fuse box, the Electromagnetic Clutch is connected at Z7/36 same like these parts:

O2 Sensor left before KAT
O2 sensor right before KAT
Reversing valve manifold
Pressure transducer ARF
Switching valve air pump

So I just have to connect +dcc wire with one of these part for the first clutch pin connector and to ECU 1.1 pin for the second clutch pin connector.
