If I am following the OP, I think he said he purchased the plug kit with the controller and plugged in under the dash.Since he has power to the controller, I am thinking his controller is not seeing a signal from the brakes or the ground is not good. I was going to pull the manual on the controller and parts listings for the plug adapter controller to truck. Right now need to know more about testing he has done so far. I would not move to the rear of the truck to do any checking until I established power to and through the controller at the dash.

The red decimal point normally means you have power, but the controller is not finding a trailer. I am thinking your controller is okay. If you operate it manually, do you get any reading? I am thinking it is not finding anything to send power to. The reason I originally asked about the controller is I wanted to know if it was a model with diagnostics. They make things really simple.
Let's talk about your seven pin at the rear of the truck. You originally had a four pin so you had marker, signal, and brake lights along with a ground. How did you go about setting up the charge line and brake line for your trailer as you did not have them in your four pin?

I assumed that being the truck had the wiring plug under dash and the dealer sold me the harness for the rear with 7/4 prong I figured all of the wiring was ran at factory and was just plug and play??? am I assuming wrong???

That's a darn good question and I don't know the answer. The easiest way to check is to pick up a seven pin checker from Northern Tool or one of the automotive stores. It just plugs in and you read which lights are lit by turning on singnals, operating the brake controller manually, etc. If you have a hot charge lead it will also light a light for that. It is much easier for most folk to do this than mess around with a meter or test light.
Unfortunately I have not wired an aftermarket controller into the newer Fords, so without being there, I can not be much more help. Maybe someone else reading this thread can help us out. Do all the newer Ford trucks have a charge lead and brake lead for towing prewired and is it neceassry to insert a fuse or relay to activate them? I have a 2010 for my service truck, but it came with the tow package so I don't know.
Sorry,
Steve

OK I took a test light and check my 4 prong rvrything worked, then I checked my 7 prong all lights worked but no battery or electric brakes so I crawled under truck checked where it plugs into factory loom well there is only 4 wires coming from front of truck but the harness going to 7 prong has enough wires so there is the problem. any ideas on where I run wires to tie in for batt and electric brakes thanks

Clearly you are going to have to pull some wires, if you need seven and only have four.
