300SDL Climate control box wiring issue

[beltfed72]

I have now replaced EVERY single component in my climate control system sans the evap. core (thank God) I got a bad climate control unit, and chased every other part thinking I couldn't have gotten a bad unit from this source.

Here's my question:

I accidentally popped open one of the two main plugs that go onto the climate control box and the wires popped out like a Swiss watch. I have no clue which slot any of them go in, and hope I have not damaged anything "downrange" from them touching. The one that came apart is on the left (driver side) Does anyone have a pic or can you tell me where these go back in on a 1986 300SDL? I have been through the wringer on this car, and had the A/C blowing cold…then I stated fiddling because I am a total idiot.

Thanks in advance for any instruction, you guys are far and away the most helpful bunch I`ve found on any forum and surely the only reason I am even able to keep driving these cars that I truly love. I have replaced the compressor, condenser, dryer, resistor, blower, Klima switch and control unit…sure I`m forgetting something but I am not inherently a mechanically inclined person. I felt as if I`d "won" when the compressor kicked on and had cold air blowing hard after over a month of busting knuckles with Harbor Freight tools and an equal level of skill…lol

So the pbu is OK now or have you found the current one to be bad? or?

Drop me an email. I think I've got the climate control PDF somewhere here I can send your way. Might not get to it until later tonight.

MB used to publish the W126 stuff online but they had some issues.

The PBU is good, I just fiddled with the plug for whatever reason and the housing opened and wires just flew. The pegs are all identical in size, but have different color wires with 7 on each of the two rows. This is one of the two main plugs into the climate control box on the drivers side. I just need to know which wire/peg goes where. Thanks y'all (yes I did lol)
