did you install the relay and fuse in the underhood fuse box??

The relay and fuse that you find in the glove box are not for the trailer brake controller, they are to power the battery charging/constant power circuit in the 7-pin trailer power connector. There are fuses for the TBS, #33 in the passenger compartment fuse box and #17 in the engine compartment fuse box. You could start by checking those.

Since you're using an after market controller, you need to make sure that the circuits match. Was there a converter cable that came with the Prodigy to allow it to plug into the truck's TBS plug? I would check the pins at your 7-pin connector to make sure that they match what they should be activating (lights, turn signal, etc).

There is no need to 'flash' your truck's computer - that is only needed for the Ford OEM TBC. The after-market ones will/should work the brakes, but they are not 'integrated'

Did you use the Tekonsha plug 'n play harness, or make your own? I spliced the Ford and Tekonsha bare-ended harness and matched them by function, not by color.
Do any of the P2 lights come on when you press the brake pedal?

i used the plug and play harness
lights come on when i press the brake pedal
also when i use the slide on the brake controller the lights come on as well
but don't make brakes come on
didn't know if i have a broken wire

Pull your trailer's emergency breakaway pin and see if the brakes come on. Use a clampon ammeter to measure the current in the brake lines. Each of my 10" brakes draws about 3.5amps.

Hook the trailer up to another truck with a brake controller. If it works, the problem in your truck/controlller, if it doesn't work the problem is in your trailer.

Not very sophisticated troubleshooting, but that's a way to start.

got it fixed
there was no wire from the plug in under the truck in the back to the trailer plug ..
2 feet of wire thats all it took

thanks all for the responces
