OBDII question

I have no power to my cigarette lighter or OBDII but my number 3 fuse is good. What is the color of the wire that provides power to the OBDII port? I need to put my truck in tow setting deperately. Can anyone shed some light on where the problem would be? I read somewhere that there is a problem with the wiring harness getting shorts in it after some time and causing these types of problems.

Thanks.

IMO, There's probably something wrong with the fuse block if the fuse it still good.

would probably be an open rather than shorted or the fuse would blow.

I cut striped the wire and used a #22 butt connector to resplice and all worked. I don't remember what color the wire was.
