Tri, thanks for the help with the mounting sheets man, I would've been stuck without ya (or at least stuck paying WAY too much for a couple sheets of plastic)
Just discovered why you built your own harness... all of the ones (that I could find anyway) on the market are designed for cars, so the ballast power supply cables are very asymmetrical. You'd have to splice into several cables to lengthen them to even get the harness on the bike, which isn't all that worth it when you can build your own for about the same price and have fewer possible points of failure.
FWIW, the harness from TheRetrofitSource falls into this asymmetrical category, as well as the fuse holder was pretty much exposed and crimps are crap. Two of them came loose just shaking it out of the packaging bag. It's going back.
