I have placed Coax Wiring diagrams for model years 2008-2013.5 Landmark, Bighorn, Big Country and Silverado on Heartland Owners Manuals (HOM). They can be found on the navigation bar at the top of any forum screen by clicking on Tools - HOM (Heartland Owners Manuals). From there, click on Electronics, then Coax Layouts, then All Brands.
I've used a file naming convention that corresponds to the relevant model year and brand the file is for.
As of today (3-Jul-2012), there are older files in the Coax Layouts directory. Over time, I will go through these files, determine what model years they are relevant to and rename them so we are consistent in this directory.
Over an even longer time, I will try to obtain coax layouts for other brands not listed.
