Previously owned a goldwing with a homemade trlr. Trlr has a 4 pin connector. The local can am dealer states that the 2021 spyder will not support the 4 pin wiring from my trlr. Has anyone ever encountered this type of problem and if so what is the cure. I will not buy a can am trlr because i don't use one that much. Any advise or suggestions would be appreciated. Thank you hawk betts
