e63 Seats swap in E55

The fuses kept blowing so I started to check the electric connections. I figured out they are different but it was very easy to do as all you need is the connector on the other side of the car (E63) or at least a schematic of where the respective wires are in correlation to the little numbers on the connector are. If you have the connectors from the E63 then you need to cut off the one on the E55 side and match solder the E63 connectors with the colors exactly.
Now I remember one of the thick wires that used to GO TO THE SMALLER CONNECTOR FROM THE WIRING HARNESS had to be soldered to corresponding thick, color matching one on the BIGGER connector.
I'm sure I just described it very confusingly but once I figured it out it was easy and everything worked and no fuses. I think the AMG seats are the same deal.
It's very similar to the post-05 steering indicator assembly install in pre-05s which was easier than people described it, basically a new connector and match soldering the wires to the colors from the new connector to the car's side.
On the seats however, there was a thick wire that needed to cross over to the bigger connector from the smaller one. So the little connector that had THREE wires going to it will now have only 2 and one just cut off and insulated. The other 2 on the smaller connector DID NOT have to be rearranged or modified, the little connector stays the same.
The NEW bigger connector will now have at extra wire going to the very thick wire that it has in it which the old one didn't.
By the way I'm talking about the black connectors, not that yellow one which is for the airbag and seat belt and light and on the passenger side, the electric mat for the passenger occupancy sensor. The yellow connector didn't have anything to do with the seat mechanism.
What I did for the yellow connector was take the female part on the pre-facelift seat and install it on the new seat. Then I took the color coded wires from the new seat belt and soldered them to the connector from the older seat belt so they can connect.
For the occupancy sensor, I actually put in the old one under the leather of the new seat, which I took off, and so that can also plug in to the existing safety (yellow) harness.
The light I did the same thing, old light and old connector just mounted on the seat.
The airbag, what I did was leave on and then grabbed the whole old harness for the seat airbag from the old seat, cutting off the ground wire obviously that is riveted and installing it into the new seat airbag and soldering the ground wire connection to the one on the new seat.
This must have been very confusing, also, this was a pre to post facelift NON-AMG project but it should be the same but I'm not certain.
