C class seat swop electrics.

[Martin Hanford]

Hi, I need to replace my front seats in my 64 w205 estate as the leather is badly damaged. I've managed to pick up a pair of C220 amg seat which were taken out of a 2017 car. My seats are partly electric and heated. The replacement seats are fully electric. 2 of the plugs look the same but the main socket on the new seat is blank and there is an extra module on the seat with a spare socket. Is there a converter plug or extra piece of harness available so I can use these seats? The sub frame and bolt holes are correct.

Thanks
Martin
