Don't worry it is not so much expensive... You can find it on eBay around 150

Install the auto dim wiring is so easy:
Check this if you don't have it

Do you have the correct part # for the mirror that's needed to do this retrofit? Isn't there a activation button that needs installed as well or will it just be on if you put the HL switch on auto?
