I dont understand why you would need that unless you took off all the wires and took out all the plugs and forgot how the wires were.I have the same truck and I always do the plugs and wires one at time to make sure I make a mistake.If this is your ploblem let me know because i might be able to walk you though it.

SOURCE: I need help in changing headlight bulb on 2008 gmc

You have to remove the air intake filter and then kind of reach around up in there to change it. It can be done, but is a lot of work. On the duramax, it is even harder to do the driver side because of the dual batteries. You have to remove the battery, then the battery seat plate, and undo the winshield washer fluid tank and lean it forward. Then you can just sort of reach in and change both headlights. A very big pain to change a couple of headlights, but if you want HID's.... for the average person, changing a headlight now means a trip to that garage.
