I own a hitch shop, and just did mine last week. I don't agree with not using the split loom, but ya, there isn't really a good way to go. There isn't a T harness available for our rigs like a "modern" truck. Hard wiring is the only option. Fortunately, we don't have to have a dual bulb converter box. I guess a guy could go further under and tap the wires in the main harness, but I don't really see a need. Mine came out pretty clean, but you can still see my new green and yellow wires. I just ran them alongside the split loom, because I didn't want to open it. I also made my scotch-lock connections up inside the taillight housing to keep them out of the elements.
