Hello Jay,
Sorry I am getting back to you a few days late. I haven't been online in a while. I need more info on your F150. Did it come with a hitch installed or did you install it? If it came with a hitch you should have a plug and play connector under the drivers side dash just under the cubby hole. If you don't have a 7 pin plug but a 4 pin then your wiring will be easier seeing how it's all right there. Etrailer.com is a great place to shop and receive information. They have pictures showing you what to do and their customer service is really good too. Check out this link for your break controller plug and wiring.

Here is a good picture of where your plug would be if your truck has it.
If I can help anymore just let me know I will do my best.
