I need a 4 wheel drive system wiring diagram for my 02 F250

Hi guys, I've tried to find the info without posting to no avail. I have an 02 F250 ccsb 7.3L 4x4. My 4x4 used to work fine then one day it quit. A few weeks later it worked perfectly again for 1 day then quit again. Now its been a month with no 4x4. I know its an electrical problem somewhere. Hopefully a pinched wire or corroded ground or something. I am not getting any power to the switch and all the fuses that are listed on the panel are good. I would love it if someone could point me in the direction of an electrical diagram so i can trouble shoot the 4x4 elec. system. Something that listed the circuits so i can check for an open circuit where there's not supposed to be one would be awesome. Thanks and any info would be greatly appreciated.

I dont have a wiring diagram, but if you determine that it is the 4x4 control module I have one for $75. I bought a new one thiking it was the problem. It is the old one out of my truck and it works.
