I had to replace myne after I snapped the stock electric one off. I found a replacment (non electric but who cares) at a electrical wholesaler for $15.00. The dealer wanted in excess of 300$ for a new one and this one does the trick plus its flexible so it doesnt break. As RaymondJ said just take of the plastic lining in the fender and you can get to the old one quite easily. If you have any questions drop me a email.

When I first broke it I just put a huge ariel on that I got from marlows it was like $20.00 and looked pretty cool on my bullbar.
