    My 2005 F350 with the trailer brake and wire package from factory. the TBC message comes on the trailer symbol stays on and my rear brake lights stay on untill it goes off. it happens dry wet sometimes right when you start the truck then sometimes not for awhile.

    what is the problem? some people say the rear part that the trailer plugs into some have said the part in the dash. All this happens with out the trailer even pluged into the truck. .
