I am trying to loacate the plug for conecting a brake controller to and dont know what it looks like or were it may be located. thanks

On the new body style F-150, they moved it just a bit ( vs the 97-03 MY and the 2004 Heritage / Lightning models ).<br /><br />It is behind the dash, should be a gray colored connector.<br /><img src="/uploads/images/3052C94.JPG" /><br />
