Need Euro-spec telescopic column wiring diagram

[anton28]

Hey guys, my euro-spec 1992 300ce did not come with the telescopic column option, so I'm looking to install one. I can't find an EURO-spec wiring diagram showing how it's wired up and where it gets its power. I learned that the euro cars with the telescopic steering wheel have a stand-alone harness vs. US-spec cars, where the harness is combined with the seat module and switch.

So far, I have acquired a column, Euro switch, and euro harness, but I'm missing how the column gets power.

In the pic below with wires laid out, the purple goes to the switch, red goes to the column, and green is the ground, but where do the blue ones go?

The second pic with the big red arrow. Is that the harness im missing for power?

Update. All I need to know now is where the harness plugs circled in red plug in to.

Got it figured out. Here is the site that helped in case any members run into the same problem. It's in Dutch, so use Google Translate. In summary, one of the plugs goes to the fuse box, and another is left alone unless you have the memory seat option.

Many thanks for the details!
I am going to convert to complete memory package but I'm missing one part of the steering column harness.
It is item 170 in the old EPC section 46-105-7, so if someone has access to that it would be great to get the PN on it.

BTW, item 167 is #002 545 59 07

@500AMM, the harness in your diagram is p/n A1245403508, but it says that's only for models WITHOUT memory:

OK, and thanks for checking out.
That means I have to figure this out when time comes, hopefully it's simpler than anticipated.

Connect with this guy on Ebay. He got all my parts for the conversion and knows how to do stuff! He even knew all the differences between US and Euro-spec cars.

That is David Hendy... he's on this forum occasionally as well (@david hendy). Looks like he hasn't logged in here for a couple of years though.

Yes, David Hendy is the good guy!
I've bought a bunch of parts from him and he also collected all the needed parts for a complete memory upgrade;
2 seat bases w/memory motors, 2 memory control modules, 2 seat back memory motors, 2 headrest memory motors, various harness, drivers side memory seat switch w/cover, steering column cover w/switch & harness. The only part he couldn't find was the rigth side memory seat switch which is pretty rare, so I got a new one incl. the cover when it still was available. The seat bases are from a regular W124, not the specific ones for the V8s, which is a bit narrower, so I'll move the gears & motors over to the ones in my car. The mirrors are not a part of the memory package on the W124 as on the R129, which I would like they were.

All the memory seat el.motors and the control modules are specific, while the el.motor on the steering column already has the memory function as standard for all models, the only difference is the switch and harness. The rest of the gear mechanism sitting in the seat bases are the same for both W and WO memory.

BTW, I don't have any particular need for dual memory seats, it's just a nice thingy to have and fiddle with to get it up running - a mental satisfaction I guess.

Check in my owners thread, I had the steering column also retrofitted. One plug went into the seat control module in the seat base and iirc one into the fuse box.
