I haven't yet...I'm ordering those materials tonight.
That being said, having thought about it the past couple days, I think I have figured out whats going on. Basically what I have to build is a "Y" adapter...with the split part of the "Y" being the factory tail/stop/turn function and the other being the factory reverse function. Those come together with the adapter seen in the picture of the harness kit above and that plugs into the 2013+ tails.
