Again, only TSC had the adapter we needed to get our trailer and truck hooked up properly. If you find your electric brakes still won't work, check the pin location. Found we had to move the pin in the adapter to match the truck - then all was well.
Working a tractor and implements, we occasionally need new pins. TSC is the only place we can consistantly find these pins. Thanks, TSC, for keeping so many sizes in stock!
