retrofitting active seats into 2011 535xi

I bought a pair of active seats from a wrecked 2012 550xi and want to install them into my 2011 535xi. I installed one yesterday but the pin layout on the new seat harness is slightly different then the pin layout on the harness (the large yellow plug) coming from the car. Of course, the new seat shows no signs of power once plugged into the cars harness.

There must be way to make this work as the seat has all of the controls on it (rather than on the door or console as the 7 series does) and basically is getting power, heated seat commands and the SRS connectivity information from the car via the harness- I'm thinking there must be a way to change the pin layout on the harness so it works and am looking for someone with expertise in the electrical wiring / schematic areas of the car for advice or any advice on how to get these nicer seats to work in my car? The existing seats are the basic stock seats (heated).

Any help is appreciated.

I manage to retrofit comfort fully electric seats in my F10 that had semi electric seats with heating. I might be able to assist you. Please let me know what kind of seats do you have in your car at the moment. Please post the pin layout and colors of both seats. For ie:
Pin 1: red
Pin2: abc
Pn3 : xxx
