Hello,
I apologize for English in advance and specific words.

I have 2000 W203 Sedan without heating seats
i bought seats sport edition from 2005 with heating seats

i have only cut wiring from my new seat (20 cm).
i want to connect heating seats with front console from 2000.

I want to ask you how to connect every cable under the seat to the new seat - i mean in 2005 is a little bit diffrent plugs.
also i want to ask where is the plug to connect heat seat? i wanna make DIY to connect from seat to console panel.

For any advice thank you!

I recently swapped some seats from a 2009 C63 into my 2005 C230. You can read about it here: https://mbworld.org/forums/c-class-w...-2009-c63.html

I will discuss a few issues that you may need to consider in the following paragraphs. However, I have not worked on seats from a 2000.

1. I am assuming that you are not in the U.S. Due to U.S. safety regulations, the seat belt/seat occupancy system in your car may be different than in the one I worked on.
2. Mercedes appears to change the systems in there cars over time. In the U.S. cars, there are significant differences between a 2000 model (which we refer to as a "pre-facelift" model and a 2005. I don't know whether any of the changes affected the operation of the seats.
3. There are different levels of seat controls. Some only have motors to control the seat back and seat height. Others have additional motors that control the fore and aft adjustment and seat tilt. Some seats have a memory that saves three seat settings. If the seats you are installing have all of the features in common with the seats you are removing, you are likely to face fewer complications.
4. If there are many differences between the two types it may be easier to swap the foam pads and seat covers from your new seats on to the frames of your old seats.

With regards to the seat heating function:

To make this work like a factory installation, you will need to obtain a set of switches that have the seat heater control, This post seems to have some guidance: https://mbworld.org/forums/c-class-w...-retrofit.html

On my car, the seat heaters were powered by two sets of blue and brown wires (one for the seat back and one for the seat bottom) that met in a connector under the seat. I have a couple of connectors from the car side if you need them. I will post a picture tonight.
