Whoo Hoo. I got this done. It is actually quite easy. I bought a set of used mirrors, door switches and drivers side trim panel from a GMC truck. If you buy used parts from a truck with this option you do not need to have the dealer flash it. All I did is bolt the mirrors on and install the switches from the DL3 optioned truck. I will get pics and try to do a write up of the process this weekend.
What you need from the existing DL3 optioned truck:
Mirrors
Drivers door switch and bezel
Passenger door switch (You only need this if you want to avoid a trip to the dealer for a flash)
The drivers door switch is physically different. It has an additional switch to fold the mirrors. Because of this you need the trim panel as well.
While the passenger door switch is the same part number for both options, It has programmable memory module with the mirror options flashed to it. If you do not change the passenger door switch, Your passenger door mirror will not fold in. If you can not get a passenger door switch from a DL3 optioned truck, you can go to the dealer and have them flash your existing switch.
As an added bonus, I now have the Park Tilt option in the DIC This option was not there before. I thought I just may not have noticed it so I put the old switch back in just to check.
