Coach Controls Wiring Harness?

Well, let the **** show commence. Wiring underway.....

I've decided to connect the simple things prior to mounding he box in my car. Get all I can without craning around under my dash. Little studying to figure out how I'm going to go from Mopar steering column to GM plug...but I think I have it figured out. Trying to make things a clean and tidy as possible. We'll see. The directions, thus far, are pretty freaking awesome. That little box is more than just a fuse panel, it's a control center.
