I just ponied up the extra $15 and bought it straight from the stealership parts centre by my house ... I'd let you know the part number (cause the plastic wrapper is still in my garage) but it *may be different as I have an '07 sedan.
I bought a whole set of OEM fog lights for cheaper from a dealership just for the lens, because they were getting rid of them and the lens are interchangeable with 06-07. I will never use the 03-05 switch. I'll sell it to you, it's brand new. Just PM me.
