Pinout 05 silvy

[Arctic28!]

I have a 05 silverado 5.3 LS EXT cab. I can't seem to get a wiring pinout from the steering to the underhood fuse panel to the fuse box. It was crazy with 3 alarm systems put in and cut out. two radio systems put in and cut out!!! all spliced back together. with bubble gum tape it is sticky everywhere but where it needs to be.

 

 

 

 

I can't seem to match up my pinout to my truck. the 03 and beyond manual seems to be missing some diagrams or i am . If anyone knows where I can find pics or documents please can you point me the right direction .The connectors from underhood fuse panel to the passenger side pinout or at least a web site, thank you.
