Full electrical seats conversion

Hello,
It is my first thread here, so I would like to say Hi to everyone.

Yesterday I bought leather seats from saab 9-5 aero to my 9-5 MY00, non aero version.

And I have some questions concerning this modification.
Firstly where I could find any information how to add wire to new seats? My old ones are full manual.
Secondly I bought Uk version so i have to convert it to Europe version. Is it very difficult? I should only remove memory "box" from right seats and install it to left one?

I hope someone could help me.
