Older trucks MIGHT have features hidden.

I have no idea whether this applies to anyone else here but my recently purchased older truck has power windows as well as door lock and window lock buttons. Wishing for power mirrors after my first tow, my mechanic observed that "hmmm, that's strange you don't also have power mirrors. Usually comes with power windows." So just for the heck of it I called GMC's 800 number, gave her my Vin# and sure enough, while my truck didn't come with them, all the wiring including the plug is just sitting there, under the pop-off bezel (the plastic covering on the driver's door rest).
Further sniffing around revealed that this is apparently not uncommon. That it would be prohibitively expensive for a car maker to produce a differently wired door that didn't include power mirrors or some other power feature only for the vehicles that don't offer that feature. So they use the same wiring for all doors of a certain type, just using a different plastic bezel that, in my case, just doesn't include the two power mirror buttons.
I got onto eBay and found a used bezel that has all my existing same buttons, the spacing looks exactly the same, but it does include the power mirror buttons and listing says it'll fit my truck. Will see when it arrives (praying because anyone towing could reeeally use power mirrors!) But hey. This is just good to know that a given vehicle might have actually come fully wired for something that it didn't offer in a given model. (Seems strange, but maybe that's how they structure their pricing to encourage people to buy a next model up.)
