Doors: Don't know if they have one here, but on duramaxforum the user towmaster did a write up that shows you how to get your doors apart in like 5 minutes...very good DIY....it's what I used.
Steering Wheel: I just disconnected my bulbs...I had 3MM LEDS bought, but for the life of me could not fit 2 leds and 2 resistors inside those little buttons....if you figure out how to do it, let me know! And also, read ALL airbag warnings before you decide to take off your steering wheel!
I'm about to start small, by replacing the steering wheel lights with some resistorless leds..
God, I hope this works...
i cant find anything on how to get the door switchs out
