Need help with powering seat with external power source

Hello,

I have a spare 02 TL-S passenger seat, I'd like to "jump" the seat to slide/recline with external power source (a 12v battery). I couldn't figure out which pins on the big grey connector requires power to do that, or if it even possible at all. I searched and found some wiring diagrams but it seems a lot of pins need to connect to fuse. Any experts can chime in?

Thanks!
