Thanks for all the suggestions. My trailer brake manual is from Active Tech of Texas. Not the same as Carlisle????? Anyway I had new wireing run in the truck to a new plug in the bed....same result. The Ford people say their system works and the DT dealer says the brakes function as designed. My guess is I need something like the Carlisle thing but I'm hesitant to try it on a non Carlisle system?? I think my best bet is a whole new brake controller (not Ford) in the truck.
