My Jeep has the ability to program this, and it also has the high end stuff in the cab..... Sound, leather, controls on the steering wheel and some programing thats in the owners manual..... my 04, 04. 5 and 05 SLT's 3500 dually don't have this... . in the manual you can chirp the horn and or the lights when you lock and un lock but can't program the lights to stay on during the unlock cycle of the trucks... .
On the Jeep and I assume on the high end trucks since its the same computer and package just a different dash you can program if its on or off... my computer turns everything off after about 1 min if I don't touch it... .
I leave the lights on, the wipers on, they cycle only when water touches the windshield, its so seamless and works so well I just leave the stuff on... . only when I go through a car was do I turn it off... .
I've ordered a new 08 and put these features on it as well.....
