R129 m119 lower engine harness

[Dmisem]

Dear forum, could you please guide me where to find the pinout/wiring diagram for m119 on r129 1993? I took mine out - it’s completely rotten/desintegrated, need to build new one . Thanks a lot.

When rebuilding my harness I used this thread as my main resource

Thank you very much for the advice. I had no problems removing the harness. Just need the pinout to confirm the correct wiring.

This is for the W124 upper harness, but the R129 should be similar.

EDIT: ooops, OP wanted the lower harness!

I am posting this for interest sake. I have just completed my own successful rebuild of a 92 500E wire harness rebuild. What an experience! Here's the scope. I own 2 500's a 92 and a 93. The 93's harness went crook about 3 years ago and I bought new one for about $650 from the dealer and...

Thank you, any chance you have the same for the lower harness? I have the top one fixed already.

Why would you need this for the lower harness? There are only 4 wires besides the main battery cable.

Schematics for the W124 are in the FSM here, look at the LH-SFI schematics. Not sure what the R129 is like and there is no PDF service manual for R129 that I know of.

thanks. I just would like to make sure that 4 are in a correct order.

Take a photo of the wire locations before removing them from the connector. Hopefully you haven't already taken it apart...

If you read further down that thread there is a post by “duh_vinci” with the pinout

ECU schematics are at the link in post #6 (link fixed now, ooops).
