Does anyone know what is required if anything before backing up this trailer with surge brakes? I am trying to decide if I should get the optional brakes with the Pro Guide V16 SC. I've been told it has a 4 wire connector which means there is no solonoid to release them when in reverse.I was also told something about having to remove some pin prior to going in reverse. And yes I have talked to Tracker sales people and they dont even think brakes are needed and I am not convinced they know which boat uses what kind of brakes.
