'06 ford f 250 keyless remote and lights.

I just bought a used Ford F-250. My GMC I traded would turn the headlights on when I unlocked with the remote. The Ford does not do this and looks like it can't be programmed to do so. Does anyone know of a wiring trick I can do to make this happen. I'm thinking that I could hook the headlights to the signal to the interior lights because they come on for 30 seconds when I unlock with the remote. Any help/advice is much appreciated.

There was a guy here last month with an Expedition, wanting to do the same thing. He's very smart, and his posts show his progress in great detail. Look here at all posts from user "rtm038." https://www.the12volt.com/installbay/search.asp?KW=rtm038&SM=1&SI=AR&FM=0&OB=1 It's especially good because you both have Fords...pretty much everything in all of his posts (other than some wiring colors being different, of course) should be applicable to your truck.
