The service tech told me that I should rewire my trailers from 6pin connectors to 7 pin connectors that the Tow Command system is not designed for an adapter. Now, the lights work and if I pull the brake lever on the command unit, the trailer brakes will work; as it says trailer disconnected on the dash. Has anyone else had this problem? Does it make sense that this should be happening to anyone?
BTW, I have tried 2 different styles of adapter plugs. 1 from U-haul with their label on it and another from tractor supply that has lights on it showing power to everything.
I haven't had the problem you describe, but I immediately rewired my trailer for the 7-pin RV type plug as soon as I got this truck. I figured I'd probably
never tow the trailer with another truck. It works flawlessly. Something I
really like about the '08 integrated controller is it actually modulates the
trailer brake pressure according to pedal pressure. The add-on controller
in my other truck didn't do that.
