Since they are on my 99 F150 i will explain. they steering wheel is wired already, they are nothing more that back lit, and have been engineered already, back in 99 at least.
Power to windows after key is removed, before door is open: you turn the key off, get ready to get out and wife says, "oh honey, my window is down again...just a convience.
Same with the radio, you turn the car off, ready to get out, your favorite Steppenwolf song comes on, what do you do, you sit there with you hand on the key waiting for song to end, leaving the car running just to hear "magic carpet ride" one more time. You can shut it down, listen to the radio, roll down the window, sing along for all the world to hear, roll it back up, all with out haveing to shut off the car and switch to accessery position on the ignition, missing precious lyrics all the while.
I know these are minor things in life when you have a high HP car under your seat, but lets face it, the tech is out there, we own the top of the line Mustang, why would it be omitted but standard on a taurus ( i am guessing here).
How many people get in your mustang for the first time and go "oh, not alot to it in here is it?", "kinda plain" (granted by third gear they are sayin "Hell yea!!"
I never thought i would talk about something so much...
