Need 7-pin plug wiring schema, no power to trailer brakes

Just last night when I went to hook up my dump trailer to bring it back from a work site, I plug in the 7-pin plug and NO CONNECTION to the brake controller!

All my other lights worked (signal, running, blinkers), but the little green light on my brake contoler would not come on no matter how many times I reconnected the plug and wiggled it around.

I need to find the wiring schema of the plug to find the power pin to see if power is going back to the wiring harness at the back of the truck and to see if I have a break in the connection in the trailer wiring.

Also, could I have blown a fuse? Is there a fuse in the factory wiring going back to the back of the truck?
