I purchased a trailer wiring harness for my 2012 HD Tri Glide from Open Road Outfitters. Being that trikes have a 4 wire system and the trailer has a 5 wire system I contacted Open Road and was told what kit to buy and was also told that the trikes wiring harness is a little differant than a regular FLHTCU. They said there is another AAMP connector ahead of the one under the seat. Does anyone know where this is located, before I dig into this?
