I took the advice from kahearn and bought a hub from uhaul to integrate my turn signals. I have the turn signals working, but no brake lights which is kind of important. I have the trailer side hooked up to the two blue wires coming out of the back of the bulbs, and the green and yellow wires on the vehicle side of the harness are also connected to the blue wires coming from the white connector on the left hand side of the bike. The only thing I cannot figure out is which wire to hook up the brake switch to. The turn signals work, but aren't as bright as I had hoped, but I have no brake lights and those are kinda necessary.
