OK, so that didn't take me very long.....
After reading everywhere that it was printed on a control module in the vehicle, and finding that there just isn't one in the back section, I started looking around and trying different 5 digit codes that I found around the truck. Ended up being on a white plastic box directly over the brake pedal (although kinda far up in the dash). Number was printed nice and large and plain as day. Only 5 numbers on it, so no having to grab the last 5 of something. Very easy once you know where to look! Locked my doors, gave it a whirl, and voila! So, if you need to locate your code, look under the dash with a flash light, straight above the brake pedal, or at least in that general vicinity. Should be a white plastic control module with several bar codes and long numbers on it, then one large print with 5 numbers. PM me with any questions.
