Hey guys,

I am looking to put a really cool horn into my S40 and it seems basically impossible to get a wire through to put a switch inside the car, and I realized that I have a button in the car for fog lights, although my car doesnt have foglights...

I assume that there is wiring coming from that switch that leads through the firewall, does anyone have any idea where those wires end up at?

Thanks a lot,
Jason

 

And I don't know if it helps but it is an 08

 

any help???

 

It may be prewired but the software will not be active to make it work.

 

Damn. That would have made my life so much easier. It seems nearly impossible to get a wire through.
