Today I was able to wire in my trailer lights. I bought a pair of tail lights at Car Quest and a used harness at a salvage yard. I decided to upgrade my old harness plug to the newer style that was on the late 80s Chevys. Plus, the one I bought from the salvage yard had a trailer hook up already wired in. I like how it turned out, still not in love with the flatbed, but the utility of it is going to be nice.

My messy work space, trying to sort through which wires go where.
Lights mounted and working! Now to bolt the bed down...
