Just finished this job! I was nervous at first but ultimately pretty easy. This forum laid it all out, and with the suction cup, the mirror came right out. I installed the blue wires closest to the window, as I found that on here and online. I used a blow dryer for 5 min just to warm it up as a safety precaution. If you're nervous, spend the $10 for the suction cup and you should be good. Total time for this was 30-40min. Love the truck, but did not like the chrome mirrors as it is to much in my opinion, not anymore!
