Based on what was occurring when I turned on the lights, used the turns signals etc. I was able to determine which wires I had crossed by comparing the Bargman diagram vs. the 'Standard RV' diagram. I rewired this morning and got all the correct functionality. I still however, have no brakes.

Here is a condensed summary, should anyone have any further input:

*Truck - ALWAYS detects trailer, I never get 'Trailer Disconnected' message.
*When brake pedal is held down, I get a single bar on the output that usually drops off after a few seconds.
*Manually squeeze the trigger, output bar fills, but drops off after a few seconds. This usually ends in the 'Trailer Brake Wiring Fault' message.
*During the very brief periods when output bar shows activity, it does feel as if the brakes are activating
*Brakes work fine when breakaway cable is pulled. (This is what prompted the pigtail swap).
*My truck activates the brakes on a buddy's trailer. His truck DOES NOT brake when connected to my trailer.
