Default Can I use the heated windscreen wiring for aux lights?

I don't have a heated windscreen installed but as you know the wiring is there. I have read that you can get juice to this wiring by getting a switch for the dash and installing a breaker in the empty space in the under hood fuse panel.

Also read that you have to get the dealer to reprogram the BCU if the heated windscreen isn't a factory installed option.

SO.... If I get all of the figured out how would I go about wiring lights to the existing windscreen wiring?

There are plugs on both sides of the windscreen and that makes me wonder if the circuit would be completed by the heated windscreen OR if the left and right side of the windscreen are heated separately. This would make a difference as to how I would wire the lights.



Thanks Yo

I tried this with my Hellas and I also enquired about a while back. It did not work for me and from what I remember it's something to do with the way the power was sent to the heated window through this switch.
If you figure something out let me know. Seems like a waist of a good switch.

I will keep you posted for sure. If I can get power to the windscreen plug I think I will be good to go, also seems like a much easier route than having to actually wire the lights!

Check the gauge of the wire and the draw from your lights. You don't want to pull to much from them and cause a fire.


I would suggest just wiring them and putting a discreet switch somewhere.

Thanks Dane, I can always count at least one or two "it won't work and by the way I have never tried it" replies.

I'm not saying it wont work. I just said check it to be safe, the wire isn't made for that much draw. Do your research on it and if it checks out you should be fine. Pull the stick out of your ***. I work with electrical every day at work, its better to oversize everything than have it undersized.

I just hope he doesn't bring a fire extinguisher when it actually happens.

And the expected second "never done it, won't work" poster arrives right on queue.

Congrats boners.
