M-sport seats swap – second connector?!

[martinsnajdr]

Hello,

my first post here. Bought Z4 Coupé 2 months ago.

I have been able to source a manual heated M-sport seats for my Z4. I have manual heated standard seats in mine. I have seen some YouTube videos how to swap seats on Z4. After checking my seats at the bottom, I have noticed another connector hanging from the main yellow connector base. Do you know what is it for? Both seats have this unplugged connector. From the videos it seemed like the only thing I should do is connect the big yellow one. The other end of the cable (with that connector) ends in the yellow one (has that gray sticker).

Thank you.

That is the connector for the seatbelt pretensioner

Oh, never guessed that. Thank you so much! So just to make sure (so i don't make some silly mistake):

I will remove my current seats, swap the sealbelt pretensioners on the M-sport ones and connect it, right?
