I have a 97 Wing with a motortrike kit on it. I want to pull a small trailer and it has a hitch but no wiring harness for the trailer lights. What is the best way to get the wiring back there? I was looking at Cyclemax and they sell a trailer wiring harness (Item B2-448) and the pin harness converter (Item 45-1848), will this still work since it is now a trike or what route should I go to get it wired?
