Looks like it was a bad BCM, but have other wiring issues amazingly enough. Does anyone know if engine wiring harness are build sepcific or will anyone from same make and model work. Tired of soldering in weird places and several connectors are bad.
Alternatively anyone know where to find pigtail replacement connectors? Specifically in this case front right wheel speed sensor connector.

 

Sometimes pigtail connectors have Mercedes part numbers. On eBay sellers have pigtails and wiring harnesses available.

 

tracking down an abs wheel speed sensor and that should be all the wiring fixed. Now on to the PCM/ ECU service manual is telling me that it is not working, but I am a little suspect of that since it runs and drives fine. Just a mess of lights on the dash still. Anyone recommend a good ECU rebuilder?

 

Anyone local I could test my DRB3 on just as a sanity check? Plano TX area?
