e91 manual heated seats retrofit

mmarco78 · 01-19-2023, 03:24 AM

Hi everyone, I am picking up heated manual Msport seats to retrofit in my pre LCI 330XD. I undestand I will have to add some wiring to get the lumbar support and the heating to work. As I want to retrofit them as neatly as possible. I would like to buy the original BMW pins to crimp and add to the wiring. Can anyone help me by telling me which ones I'll need?
I think it could be:
61138364842
61138364844
61131383776
61131393724
Anything else I could need to attach to the fuse/junction box?
Thank you all in advance, any info is appreciated!

Thanks for your offer, it's interesting. Considering I have base model seats with no lumbar support, and I will retrofit Msport seats with lumbar support and heating, would I have to buy both sets of harnesses? Are they color coded like the original wiring, so even a dumbass like me would be able to install them?

well, i forgot that my wiring from LCI car, and your car is 2006 MY, so you have old fusebox with different fuse map, and sometime different pins.
So you also should keep in mind which seats you want to buy, from pre-2007 car or newer

I am picking up the seats over the weekend and will post the pictures here, so maybe we can sort something out. Thanks a lot, i the meantime!

Retrofit has been progressing well, thanks to the info a lot of people on this forum have given me; thought I might share some pictures!

I feel you mate 😂
However, please note that the first image is what it looked like 10 minutes later, with all wires tucked away. Today I plan on vacuuming the car and putting the drivers seat back in, next are the fuse and junction box connections.

Asking for some more help. I need to buy the terminals going to connectors:

X11003 + X11005 of the fuse box
X14270 of the junction box

as per below picture. Does anybody know the product numbers, so I can order the correct ones from BMW?

Hi everyone, after doing the retrofit and coding the heated seats, I get lights on the buttons (which stay on, as I've read they turn off quickly if they sense something wrong), but the seats don't work. There is no movement and no clicking sound from the seat modules, on both sides. Could it be that my junction box doesn't support the PWM function, as I've read there are different versions? I am 100% confident the wiring is correct, and the fuses are all new, plus the chances I crimped the connectors badly on both seats are very very slim.
Lumbar bolsters wor a charm, luckily...
Can anyone please help me troubleshoot?
