(10-29-2009, 07:39 AM)E300TSC Matt, I have it listed in my tech notes at home but I'm 99% sure that even though the colors don't match, the pin numbers DO correspond to both pumps. I think I also have the corresponding ECU pins listed.
Excellent - I look forward to your confirmation of this info. I have 3.9k Ohm and 4.7k Ohm resistors in stock.
If this were any other car - I'd just hack into the wires (carefully) and give it a whirl. The thought of shorting something out with this MB makes my stomach turn.
Going off memory from last night...
There were 5 used conductors out of the slickly designed round 7 pin connector. (this matches what we're expecting based on what our friends across the pond found...) I had a yellow, white and red wire, two brown/whites and a blue/red (?)...and a small bundled bit wrapped in black... Obviously - some of these wires are on the same pin...most of them terminated at or near the ECM connector.
I didn't want to test for continuity by having to stab into wires - that sort of thing can bite you in the butt down the road if corrosion sets in.
Beers,
Matt
