2010 TBC wont see trailer
2010 f-150 with full towing package no TBC installed. I intalled an OEM TBC and took it to the dealer for them to flash. Everything works on it except the trailer brake. I see that it sees the TBC when I go through the setup on the dash. It charges trailer batteries and all lights work. The dealer is telling me that I must have a bad wire , it took them 1.5 hours to flash the TBC which should only take a few minutes. Any help is appreciated
