What's this for?

[Ryan]

Greetings all, I was after some advice.
I've been retrofitting an OBC to my Z3 and Last night I was looking to connect my Air Temperature Sensor. I found the connector on the drivers side behind the headlight. However when I was there, I found another 4/5 connectors to which I have no idea what they are for. Can anyone advise? I will take a picture tonight and share.
I assume 1 is for the headlight washers, but what are the others?
Thanks

Possibly use the same wiring harness for global market and I think usa have different side lights. Maybe to do with that

Possibly air con. Possibly secondary air pump.

As others have said universal loom covering all options. If you like match the colour puzzles the wiring diagrams are on this site http://wedophones.com/Manuals/BMW/1998 BMW Z3 - M Roadster Electrical Troubleshooting Manual.pdf

Here’s the culprits

first pic is for the heated washer jets I believe.
Can't remember the others.

@Brian4 I did notice an additional connector down towards the fog light which I would have thought for washer jet. These other 4 are spares. However not all 4 are replicated on the other side, so I wonder @mrscalex is right and they are for Air Con?

I'm pretty certain he is right The auxillary fan has to plug in somewhere.

You mean you don't have air con?.... How do you manage?

With the top down and the sun cream on

Good answer, but A.C. sure helps with the demisting! I actually drove home from some events this summer with the top down and the aircon on it was so hot. And yes, suncream is a must, and a peaked cap!
