My husband has a F3T and we have an Aluma trailer we want to pull. The trailer has a 5 round connector and from what I've been told from the Spyder dealership the bike has a 4 square. If we wire the bike and trailer with a standard 4 flat connection we will lose the brake light on the trailer and the turn signals will act as both turn and brake lights. Is there anyway to be able to keep the brake and turn signals separated? Thanks in advanced for any help.
