Yes, thanks. The brake ctl is factory installed, the truck is super duty with a tow pkg. -- never used, also has four switches on dash right next to brake ctl marked AUX 1, 2, 3, & 4, they have small lights on them that light up when I flip them up, these are factory installed also. TK is 2006. they don't pwer up the wires. ------- ?????
