Hello, i recently bought for my bmw x3 f25 new sport seats, they are inflatable, and also have some feature i do not know (ill post a picture maybe someone will tell me?) My old seats had nothing, so after pluggin it in its obviously not working. So how to make it work? Im pretty green with electronics but i wanna give it a try myself, any tips?

You probably need some coding to add the option on the VO of the recipient car.
You need E-SYS to do this

S488A Lumbar support, driver and passenger
S489A Lumbar support, passenger, electr.

After you add these option codes, they should start working. Not sure what option S489A exists since the controls come in pairs but... ohh well..

What about the wiring? On the seat's yellow joint are pins that are supposed to go into car side but on the car side there are no wiring so the pins have no power and i was suspecting they're responsible for moving the seats around and inflate, isnt it?

I doubt there's any coding to make those features work. Let me dig out the wiring diagrams and see what I can figure out.

At least as of 2014, power lumbar is completely self-contained. Power from red/white. Brown is ground. Make sure there's a 10A fuse in #67.
