ECU Wiring Diagram

[pghjake]

Anyone know where I can find the ECU wiring connection numbers or diagram for the 451? I found the wire colors and numbers for the 450 on Evilution, but can't seem to find anyhting similar for the 451. There is a partial list in the AREA 451 crusie control installation instructions, but only for the specific wires used for the patch cable.

I can post up pics tonight, it won't be connector view so you"ll have to find the pins on the ecu yourself. Numbers are on the ecu(ME-SFI) connector(s) I believe, so its just a matter of counting pins to figure out what is what.

Exactly. Thanks in advance.

Thanks Steven, PERFECT. Exactly what I needed. I did have a violet wire you didn't list, but it found a home in #64.

Ooo, I see you were editing your list as I was wiring up, and I guessed correctly. Just to keep everyone in the loop, here's the list for the small ECU connector.

I'm also looking for the wiring diagram But is it me or... is the picture of the ECU wiring diagram not posted on this thread nor on that link SmartieParts posted?... I see the pin out and the colors of the wires in letters but... not an actual diagram.. =X

I think you would need access to Mercedes Benz WISnet software. There are a few illegal downloads floating around Pirate Bay, et al. Probably won't be too easy to get the passwords needed to install, and most likely the version will be German as the illegal copies are mainly from former soviet bloc nations. Maybe you could make friends with your friendly local MB service technician?

You are correct. From the author's post elsewhere, I knew what he was looking for.

Regarding the diagrams posted above... the site may want to be careful because that is copy protected material that MB would NOT be pleased about being posted on the web. Just saying.

Sorry about that.
