I think your ECU connections will be the same as Oilgle's ML270, but the easiest way is to meter backwards from the MAF and EGR transducer, using continuity and DC voltage check.
Disconnect the MAF, EGR transducer and ECU plugs then find the appropriate wires.
It's difficult to describe but easy in reality.
Looking back in the thread shows the 270 connections to be as below. the 320 may well be the same, but will need checking before committing.
The wire from MAF pin 5 to the ECU Pin 24 plug 2 is Brown/White.
The return wire from the Vacuum Transducer to ECU goes to Plug 3 pin 50 is Grey/Black.
The 12V Red/Grey from ECU Pin 37 plug 3.
i see an ebay opportunity for someone here! make up the resistor/diode mod with wires and instructions and hawk it on ebay. parts cost = pennies, could sell for £10-£20.
Do you think Oligle would drive 100 or 200 miles to fit a few resistors for you?I wish i have the tech know how, i could make lot of money out of this, but for me who is just a Mercedes owner, i think this is the END of the road.
I wish Member Oigle is in the UK, i'm sure he'll help, but for UK members i'm not sure, all in all i must say the site is for the tech guys and not for owners.
Thank you to everyone

Sorry to sound terse, but if you aren't prepared to do anything to help yourself, then you will be disappointed by not finding help.
This is a web forum and the country is a big place.
I'm not angry with you, but this is a remote forum so we can only offer remote assistance.I can understand, please don't be angry with me,
I can understand, please don't be angry with me, i only mention Oligle because he advice if i can drive to one of you guys so i don't mess with the ECU, and i've tried contacting few people in my area but none knows how to do it.
I'm not expecting anyone to drive 100/200 or more miles to come and fit few resistors for me, i'm ready to go to anyone and pay to get it done.
Dieselman, you have done a great job, without you i woud never know about this so don't be upset with me, anytime i lift the bonnet i can see this thick black tar and when i look around the ML, everything is neat and seal, don't know where the ECU is, and this is my first Mercedes that's why i'm nervous.
I hope members will understand my disappointment and the reason why i need help so badly.
Thank you all
Yep. Definitely injector blow-by.I am a bit concerned about the above underlined statement, mate. The issues with the EGR don't manifest themselves externally. Perhaps you have a problem with injector/s leaking??
Maybe another good reason to make an appointment with a good indie and get it looked at.
Yep. Definitely injector blow-by.
Injector was done 6 months ago, when stading in front of the ML on my right hand side there is a hose and black oil coming out of it and just under the hose there is round thing like Exhaust box and is full of thick black oil by the inlet manifold area.
