I had a trailer wiring harness installed at the dealership. When first installed and tested with a test light, all pins on the 4 pin connector were cold (no power). Returned to dealership & now I have: with key on the pins are cold. With engine running all pins are hot. None blink when turn signals are activated. Dealership says that’s normal, it’s because I’m using a non OEM trailer. I say the connections need to be working at bike before I even connect the trailer. When I connect my 4 square to 4 flat all I get on the trailer is constant brake & running lights. HELP!!
This is my first post, so hope I’m in the right spot🤞
