This topic was a WIP research about how to do the electric seats retrofit. We discovered there are so many car configurations that it's impossible to do 1 guide for all. So, we prefer to share our notes and you must do your own research to validate your car and seats FROM -> TO configs.

sorry. which pin you dont have in cable from car? best would be add some pictures. full seat scheme with description is on 3rd. page.

http://www.e90post.com/forums/showth...=480313&page=3

as you can see. pin 4 is big one...for heating. I also think its for adjusting electric seats (front, back, up,down...etc). coz another + cable is on pin 7 or 9, which is for side bolster and lumbar, as you alread wrote.

thanks for you response ,i don't have cable in this pin in the car because my original is not electric... i post photo the news seat and i what controlled ....
i thinks this pin 4 is adjustable seat electric but i don't know when i plug in fusebox.... the pin 9 and 4 are exchanged when i see the shema in page 3 because normally pin 4 is for heating or seat module but if you see in wds for car 2011 the pin 9 is for heating module and pin 4 only for seat module....
i am confused only with this pin 4
my drive seat have seat module but it's ok

Pin 4 is for power. Connect it to pin 7 or pin 9 and you will be good to go.

Thank you so much to the OP for this write up. I was able to get my seats in, and the can bus wires were the hang up I was having. They work great, and my 323 is moving on up. Cheers
