Hey dude,
First off, I gotta say, bang up job on this truck. For working with what little you had to go on, very well done. The wiring looked clean and well laid-out, and the pint and home-made lightbar turned out really nice.
A suggestion for the future, if I may provide one:
I realize wiring is expensive as hell right now, but for purposes of clarity and allowing others who may work on the wiring in the future, use multiple colors of wiring to distinguish between circuits (e.g. Red for hot/positive, black for ground/common/negative, blue for one circuit, green for another, etc.) so that way you're not having to chase down stuff by guessing later on down the road.
But again, with what you had, I'd say you knocked it out of the park and then some.
EDIT: Also, if you'd like, I have a pair of amber Whelen LIN3s that I'd be willing to donate to you at no cost for use on the rear if you need them. They're four-wire control and have flanges with them. Just let me know if you need them, and I'll send them your way.
