ABS Trailer Brake Idiot Light... 2008 ProStar

[linadin]

i have used 3 new cords trying to clear it. the other day i just took the dash apart and put a electrical tape over it till i can figure it out. I looked thru the diagrams trying to find out what would cause it as it does seem to go thru the cab computer as well as the abs computer. i really do not want to have to replace them.
