UNK Fuse

Yahoo Message Number: 16898
I have a Bully Dog gauge tuner I use occasionally on our 2009 MS36 Seneca. Now the tuner won't boot up when I connect the OBDII cable. It will boot when I connect with USB to a pc.

So, 12vdc is not coming through from the chassis. I've tested for voltage at all the fuses under the hood and didn't find any were open.
So, might someone have a wiring diagram that could identify the specific fuse which should be powered with the supply 12vdc so I can narrow my search?

Thanks for any guidance.

Check the fuse controlling the cig lighter, accessory outlets, and OBD2; #8 (POWER POST) on the passenger panel.

The power for the OBDII plug is usually the same fuse as the cigarette type power plug on dash. It fuse is on passenger side of dash. Lower panel is removed by taking 2 screws out that are at bottom of dash. 10mm hex heads. Location of fuse are in manual. Should also be a diagram of fuse on back side of panel that was removed to get at fuses.
