What's this connector for??
 

Checked a few X5, none have anything connected to it.

Do you have a picture? Where is it located?
Mine has plugs under the rear seat. I know they for heated seats. Only the fronts seats are heated on mine. However, I may look for a heated rear seats someday.

This little guy is by the firewall. In the front left corner. Not far from EWS module.
That green little thing you see is the front speaker they cal gong speaker as well.
Let me see if I can find more pics.

:worthless:
Sorry, the pic is not posting. Is it too big? Click the upload button. :dunno:

I can see both pics fine. Don't know what the harness is for though, sorry. Looks like the keyed 4pin connectors BMW uses for all sorts of things.

I can also see the pics fine.

If you've looked at several Xs and didn't see anything connected the best way would be to look at a wiring schematic to know for sure.

There's many different options between the X5 lineup itself and different markets. Maybe that plug is all the rage in Europe :D

As crystalworks said it's a common connector which makes it a little more challenging to identify from looking at it.

Oh, sorry. I'm behind a firewall. The pic is linked and not uploaded. I check my phone and saw the pics.

Hehe yes it's a little tricky to figure out which wiring circuit it's on. But I'm sure someone will know ��

Hmm....i'm curious too. So lets see if I can get the wire colors correct.

1. BROWN
2. PURPLE
3. BLUE
4. BLUE/WHITE

...you guys see that too?
