Replaced the wiring harness Friday night, only took 45 minutes... At night, so if you do it during daylight it would probably only take a half hour or so... When I reconnected the battery, the clock was 45 minutes slow, so that is all it took... Very easy to do, much easier than replacing the plug wires... If you are thinking of replacing your harness, don't sweat it, it's really very easy to do. Typical Mercedes design, you simply cannot plug anything in to the wrong part, the connectors are physically able to only plug in where they are supposed to.

About the only problem; it didn't fix the stumbling!

It does seem to maybe idle a little smoother, but then, it always did idle very smooth. The only problem is I need to replace two plastic clips, since they were completely brittle and broke taking them out, and the new harness didn't come with new ones... The new part was made in Poland, looks to be very good quality... My old harness was VERY brittle, I would be unhappy if I saw this come off a Dodge or a Chevy... Cannot believe it came off a Mercedes... Absolute crap!

The ABS brake code was a EA CAN communications error, not a wheel speed sensor malfunction... So I erased the code, and I will have to see if the code comes back with the new harness. I didn't get a chance to see if the ABS is functioning now, I decided to change the trans fluid and filter, and Napa managed to sell me the wrong part. (They had two different parts listed, and I looked at the pictures... I picked the one that looked like my pan, and he sold me the other one...

I still need to know how the heck I can check out the ETA... I searched through the POS "Factory Service Manual", didn't see anything on it... I have the Mercedes WIS too, but I haven't reinstalled it since I rebuilt my computer. I am not a fan of that software, either... I has a lot more detail than the factory service manual, but it's such a struggle to find it... The only thing I liked about the Workshop Information System is the screensaver it adds to the windows logon...

I guess I'll search the forums here and see if I can find any info... The server was down this weekend...
