I remember reading that it costs pretty big bucks to add factory fogs after the fact. I think it was in the $300-$400 range IIRC. Ouch.
Ouch? You have no idea. Just the individual lights will cost that. Here is a summary of what the fog lights would cost you to have installed by a dealer:
Qty___Part No.______Description____________________Price
__1___84140-0C060__Switch Assy, Head__________________$103.60

I was lucky to have negotiated this down to about $600 since I had many other options installed at the same time as the fog lights. The biggest part of the labor charge will be the replacement of the headlight switch assemby (left side stalk on steering column). The steering wheel has to be pulled and this involves the airbag system by default. I'd leave that up to a dealer.
The only reason I spent $600 was that these items were done at the front end of my deal when "what's another $600" seems to make sense, and I knew if I took it home and started running it without these items I'd probably never do it. In fact I can tell you today after 7,500 miles I wouldn't dare take my truck to the dealer to have this stuff installed. I'd probably aftermarket the fog lights and install the mirror and backup camera system myself. But in the end it's nice having them now.
The wiring is already in place in your truck. Maybe somebody could just add the OEM lights and brackets and then figure a way to intercept the wiring harness and put a seperate switch on the dash. I think a seperate switch would be more useful than the OEM in that you could decide when the foglights are on. Plus, nobody would be messing with your steering column in a brand new truck.
Hope all that helps.
