OBD II port

Does anyone have the wiring information on the OBD II port? My wife's 2009 has no power coming to the port. The scanner will not turn on. I checked the scanner on 10 and it turned on correctly. The wiring diagrams in the Haynes manual does not have a complete diagram, and none of the diagrams that they have show the OBD II port. It could be just a fuse, any ideas?

Somebody put a cigar lighter element in the 12V accessory outlet and blew the fuse.

Thanks all. A blown fuse. The only things that has ever been plugged in to the socket are a cell phone charger, GPS and a small rechargeable flashlight that stays in all the time. The flashlight has been in for several years as has the one in my car. I don't know what caused it to blow. I swapped 29 and 30, I will pick up some spares today. In the 7 years on the wife's and almost 7 years on mine this is the first blown fuse. I have some blade fuses around here some where but I have no idea where, the best way to find them is to buy some more.
Thanks all

If this is the first blown fuse, there should be spares in at least one of the fuseboxes. I wonder how long it's been since your flashlight was charged(since the fuse blew).

RJ. You mean spare fuses like the ones in Oldblues picture ?
I've always kept a small box of spares in all my vehicles just in case. I used to pull various trailers and occasionally would blow a fuse.
