Yes I can help you. a little.
Firstly by telling you to bin the memory function. IF the ecu still works it's worth at least £70 on fleabay.
The switches are the same other than the extra 3 buttons you can ignore.
The wiring from the seat switch is totally different as the motors were run by the relays in the ECU all the time, but you can cut it out and rewire it.
You can also ignore all the stuff for the mirrors.
If you want to keep the memory then you basically need a permentant live feed and an ignition feed, plus some stuff to the door switches, there's a couple fo relays just for that bit alone.
