The blue is for trailer brakes, the black is 12v and the orange is auxillary. The others are brown-taillights, green-right turn, yellow-left turn, and white-ground.

A 7 pin plug has the ability for the truck to use trailer brakes where a 4 flat doesnt have the ability to use the trailer brakes. I had to pull a tandom axle cargo trailer a few times 3 years ago and got an adaptor that would plug into the 4 flat connector that my truck came with and that would plug into the 7 pin plug that the trailer came with. It would allow me to use all the lights on the trailer but i couldnt utilize the trailer brakes. If your boat is tandom axle and has a 7 pin plug, im pretty sure you have trailer brakes on your trailer. If you dont have the extra trailer brake wires right at the hitch that are not ran into the 4 flat connector that your truck came with, you wont be able to utilize the brakes on your boat trailer if it has them. Your F150 should be equiped with the ability to run trailer brakes if you only have the 4 flat plug but you have to have a brake controller to set that up.
