C63 2012, need help please! Throttle actuator connector issue

Hey guys, I recently installed a Weistec catch can at a shop I trust, but unfortunately the connector for one of the throttle actuators broke. At the moment it still plugs in but it is loose and definitely not how I want to be driving the car. I need to replace the connector for the throttle actuator, the issue is I cant see any mercedes number on it and the dealers are unable to find the part. Maybe I just got unlucky and mine didnt have a number I really dont know. I do not want to spend over $1000 to buy a new engine harness just for a connector. Does anyone know where I can get this connector or what I can do? It has been weeks now and the dealer still hasn't found it. I am really scared the car is going to be undriveable soon.

The part is not sold separately and sold only with a throttle body harness for 80:bucks.

I already looked at this part and showed it to my mechanic and it looks to be the wrong part and not the right connector, at least he said that.

Then take a picture because I am not sure what connector you are talking about, this is the one that usually breaks when you undo the throttle body connectors.

That is unfortunate, the car side not the manifold side, usually the other half of the connector is the one that breaks. It may be 905 and 906 on this diagram for the 2 connectors to the throttle body connectors, but not 100% sure as the labelling is poor on the diagram. I did it in my copy of EPC and all the other connection points tell me what they are for or that they are unused on this model, those 2 are labelled basically connector to another harness which the throttles are as the other harness connects to this harness and then to the throttles themselves, so these are maybe the connectors but best I can help on this..

Thanks for your help, this has been very frustrating.

Why do you think that it is 905 and 906 in that diagram and not another number? Are there any others it could potentially be?
I found 905 and 906 for sale here and am tempted to order it. These should be correct parts?

a guess based on all other numbers on the diagram when I look them up in epc either show not applicable to the c63 or have a description saying alternator connection or O2 connection etc so I could rule all them out except these 2.

Nice, thanks for confirming as it will help others as those connectors are getting brittle after all these years - I broke the other side on mine.
