Pulled 7way plug out of truck.

In a hurry, got distracted and pulled away from my trailer with the cord attached. The cord was stretched at the electrical box in the king pin assembly. I removed the box cover plate to see if there were any broken wires and did not see any. All lights work but now I have no trailer brakes. This is a used truck but is new to me. I just bought it and noticed that it had a new controller installed. I don't know if it was installed correctly or not. I am going to try to isolate/determine if the problem is at the truck or the trailer. I'm not much of a mechanic but will try to use a test light. The previous owner was a veterinarian so he probably had the controller properly put in so I'm thinking I have probably damaged the wires some where inside the box.

What do you folks think?

Stuff happens. Do you think the brakes were working before pulling away connected? I would think if the lights and turn signals are all working then you just pulling away would not make an impact to the brakes only.

Which brake controller are you using? My Prodigy would let me know where I am at.
