No TRl brakes

I have an 07 F350 with an integral Brake controller. I have no trailer brakes but the brake lights come on the trl, when I push the pedal.

Message on the dash says Trl disconnected. Any ideas??

Thanks Tore

You need to open the 7-way connector and check the voltages at all pins on the truck...been know to collect water in there and corrode. Once repaired coat with a good dielectric grease.

Look here for pinout.... https://www.ford-trucks.com/forums/5...g-diagram.html

Your brake lights work because they are a different circuit, What I found both on my RV trailer and enclosed trailer was a bad plug. I replaced it with one from NAPA that has a better contact setup. The original just didn't have enough spring tension to keep a good connection.

I didn't like the way the plug from the trl looked so I replaced that and cleaned the contacts on the plug from the truck.
I also checked all fuses and circuit breakers and all well.

Have to get the teast light out tomorrow.

I agree with all preceding comments.

You really are only checking one thing. Do you have power on the blue lead at the trailer (do this at the "J" box). If you do and the brakes don't work, troubleshoot the trailer. If you don't, check your seven pin cord and the connection on your truck.

Good luck,

Steve

NO Power coming out of the blue lead on the trl. Tine to start checking backwards.

Where I would start if you have a trailer with a breakaway switch is pull it and see if the breaks work then you will know which way to go from there.

Thanks Tore

When I was working and still had my business it was always a battle keeping the plugs on the trailer and truck clean and in working order, I was **** about keeping the lights and brakes working on all of them.
