Some of the 5 flat have an extra brown wire that takes lights down both sides of the trailer instead of “splitting” the brown off. In anycase, you should just have 5 pins: Ground, lights, turn/brake, turn/brake, and backup. Colors will be white-ground, brown-lights, yellow-left turn/left brake, green-right turn/right brake, blue-backup.Hope this helps, JohnJones Trolling Motor Services870 773 3474Motorguide/MinnKota/PowerPole/Lowrance/Humminbird
