Tonight I was able to get to the rear of the HU and map out the pinouts of the stock harness. (as i was typing this post in, I lost my original, so I will now provide an abbreviated version )

The goal is to keep the stock HU, and determine how to make the stock HU output a differential signal as it is currently powering the speakers. Thanks to Canuck328 for help on this point.
