Availablity of detailed parts catalog?

The Trade Motion catalog used by gmpartshouse and other on-line suppliers is a great help, but omits a lot of the little bits. Does anyone know of a source for a more detailed part catalog/list (other than the dealers I'm already pestering on a regular basis)? Looking for something that covers the 2004 HB.

An example of parts apparently not covered in the Trade Motion catalog are the rear door to center pillar wire looms needed to add lock actuators (etc.) to the back doors. TIA for any suggestions.

I have access to the chevy catalog at my work. (Sister store is Chevrolet)

Feel free to ask whatever you want a pic of, and I'll try to post it up.

Thanks - I can locate most of the parts in the GM sourced diagrams in the service manual, but it doesn't provide the part numbers needed for ordering. Here's a diagram with the rear door wire loom mentioned above; I am after part numbers for both right and left sides on a 2004 HB if they're different.

Not in catalog because apparently not available except as part of the wiring harness. Have opened new thread to discuss other options here.
