04 T2000 no power to center abs/aux pin please help

Hello everyone looking for a little help, I've checked fuses behind glove box although no manual so checked all . All seem to be fine , stripped away the plastic coil to the female pig tail on tractor all wires and connections good .
No power there , it's got to be a fuse or corroded wire somewhere , I've looked on the fire wall like the w9 but no luck am I missing something ? Also a nice clear pic of fuse panel diagram would be awesome.. any help is appreciated thanks

 

So far 141 fellow truckers and not a one has a better thought at it then I lol.... Someone else is gotta own one of these amazing miracles of kenworth ingenuity ...Ok I'm gonna stop before I hurt myself

 

Thanks for the response was hoping that maybe I just overlooked a hidden fuse or something cause tracing that up the frame rail and through everything outside in 10 degree weather ...but if nobody has any other ideas I'll get to it

 

Well I believe I found my problem after rechecking all my fuses ,( all were good) I found in the bottom right a empty slot for a fuse I guess I must have overlooked it as it was dirty to the point you really couldn't tell it was a fuse slot . Anyways put new fuse in there no more problems.. would be nice if someone with a t2000 could give me a fuse layout pic .. that's clearly visible , would be greatly appreciated
