Rear Door Wiring Harness

[sdhow]

So...got the car back from the shop...

Somehow, they managed to damage the bellows between the B pillar and the door that the wiring harness and a couple of vacuum lines run through.

Anyone know the easiest way to diconnect these so I can pull them back and through the bellows? At this point, I'm assuming I have take off the door panel and disconnect them from each device located in the door and feed this all back through the bellows.

Pictures are always a big help!

I guess what I'm asking is...are there disconnects for the door wiring and vacuum lines in the B pillar?

if i remember correctly the vacuum lines are connected directly to the pump. the wire harness is suppose to disconnect

here is a ebay link to it

That's what I thought, too, but EPC shows a manifold connection in the B pillar. I'm going to scout a couple of wrecking yards next week for some W140s to look at.

Take a look at the second picture in the eBay listing; it appears the vacuum lines from the door also connect into the harness disconnct unit, allowing for the door to easily be separated from the main body harness by this connection. In my case, I could slip the old bellows off and the new bellows back on and through the hole in the B pillar without taking the door panel off. I would have to remove the B pillar cover, though, but that's a piece of cake in comparison!

So...looked at a wreck...There's a harness disconnect that is accessible behind the inner panel of the B-pillar. Push down the locking handle and it appears to release the door harness connector from the body harness connector. Seems to be a tight fit to pull the door harness connector through the opening in the outer hole in the B-pillar with the rear door still bolted in place.

Has anyone done this with the door left bolted in place?

So, Eddie, just a 1/4" rachet extension in that little hole, turn it to the left and voila! the harness is disconnected? Is the installation the reverse of this?

Thanks again, Eddie! I KNEW there was an easier way than taking the whole door and/or B pillar apart. and it was a huge help to look at a wreck and tug and pull on it's harness before tearing into my baby!

Word of caution, though, and I know Eddie has mentioned it, the plastic retaining rings of the bellows assembly are EASY to break, so go slow and be careful...and it's a super tight fit, so I'd recommend using masking tape around the feed-thru hole in the B-pillar to prevent paint chipping during the reverse process.
