Question:
I am guess that you have a connector similar to the 5-Pole round like part # PK11502. If this is the case, you have two options. You can either remove the 5-Pole round from your Harley and put a 4-Pole flat in place, or you can cut the connector of your trailer and use a 5-Pole connector for the trailer. I imagine the 5-Pole on the bike is mounted pretty well, so I would suggest replacing the trailer connector with a 5-Pole using part # PK11501. Using a circuit tester, like part # 3808, determine which signal is on which pin on your Harley connector. A 5-Pole round will have a wire for left hand turn and brake light, one for right hand brake and turn light, one for running lights, one for ground and typically the last wire is either for a brake controller or reverse lights. I attached a review video for the # 40376 for you to check out also. Unless your trailer has brakes or reverse lights, you can omit the last wire. Once you have determined which pins do what on the Harley connector, you will attach the wires to the new 5-Pole round for the trailer in the correct positions so they will mate up properly with the Harley connector. Typically a trailer is wired using the following color code: White - Ground, Green - Right turn and brake, Yellow - Left turn and brake, and Brown - Running lights.
