No problem, some say the dealer has done it for them, but my dealer was too dumb to even disable the double honk (another forscan trick). Forscan lets us use a normal laptop with a OBDII wifi connector to change several ways the truck interfaces with you. Lots of threads on this. It is for most Ford products, not just diesels. If you wish, downloading a forscan program is free but if you want to do long term work with it there is a fee. It also allows you to observe trouble codes, operating parameters and such.
If you are ever up this way I would be happy to help as I am sure most of us would.
