Trailer wiring ?
I have a 07 Ultra. I have already installed an isolator harness from Electrical Connection. So now I have a square plug "going" to the trailer. It has six wires ...Ground, Right turn, Left turn, running lights, brake lights and an extra one that I think is used for accessories. Most/all of the trailers I have looked at have 4 wire flat plugs. I really don't want to add lights to a new trailer.Any help would be appreciated.Wouldn't you think that if they are building trailers to be pulled by bikes they would wire them that way
