Hi guys

I have recently got my ECU fixed from water damage and corrosion however some of the pins in my plugs are corroded

please can you point me in the direction as to where I could find these plugs? I’ve been looking everywhere and can’t seem to find them

thanks

hi @bbirdwell thanks for your reply, could you help in confirming that I’m looking at the right parts

500-540 & 550-590

thanks

 

If you are talking about the connectors for the Motor Electronics (not SAM) then you want to look in the "Electrical Equipment and Instruments" section 54/078.
HOME/Mercedes/1/FG/FG 211.076/54/078

Also note that you mention "pins", i.e. male connector, versus "sockets", i.e. female connector.

The image and connectors in your screenshot are for the front SAM in section 54/080. If that is to what you are referring, those numbers would be correct.

hi mate, what I’m looking for are the 5 plugs that fit into the ECU

please excuse my ignorance, just not knowledgeable enough at this stuff

 

Should be in section 54/080. Might be possible to get connector part numbers under the engine harness. FWIW, I believe I did see at least two of the plugs in the parts list.
Alternatively, you could look for a salvage W211 with a V8 motor and see if they will allow you to cut a foot or two off the harness end with those connector shells You can then de-pin the shells,, order new sockets from Mercedes, remove any corroded sockets on the old harness, crimp on new sockets, and re-pin the connector shells.
Obviously, meticulous attention to color codes is paramount.
I'm not at home right but I'll relook when I get home.
EDIT: part numbers should be on the connector shells themselves. The sockets for the wires are available from Mercedes and aftermarket suppliers. De-pin tools available off Amazon or equivalent. Crimper for 16-20 gauge wire available from Amazon or equivalents.
In section 54/078, this is listed as the female contacts for the small pins on the Motor Electronics.
It makes reference to section 54 TU 120 but I'm lost on this; I don't see a subsection 120...

 

@bbirdwell thanks for your reply on the above,

after getting the ECU fixed I checked the plugs as you mentioned above, and I ordered new plugs, turns out they weren’t e55 so the wiring was different. As the end I noticed that some of the pins were open, so managed to closed them and crimped 2/3 wires and now it’s running, no cutting off issues!

thanks for the above
