OBD2 Port

I plugged my livewire into the OBD port and have no power. Is there a fuse? If so which one. The owners manual does not list a fuse for OBD. 2008 6.4L
Thanks
Jeremy

I had a similiar issue with my 96 F-150...tied to the same fuse as the cigarette lighter. Might be the same.

Cig lighter is working. I pulled every fuse inside and out and found none blown. Could it be one of the non used fuses and factory isn't telling us, which makes it harder to use a tuner?

I have no power to pin 13. Does anyone on here know anything about this port. I tried pluugging the tuner into my 6.0L to see if it would power up and it did not. I am assuming that the pins are different on my 6.0 which is why it did not power up. I plugged the tuner into my laptop and it worked. I guess I will have to make up a bogus excuse to get the dealer to plug in thier scanner. I'm assuming it needs the same power as the tuner, they will have to fix the OBD to get thier tool to work and then I can use the livewire. I do have 12.3v to pin 16.

If it wouldnt power up in your 6.0 then its the OBDII Cable for your livewire. All OBDII's are commonly wired, just because it works on your computer doesnt mean anything, two totally different ports and cables....

Livewire is going to check the cable and unit. You guy's are right. The 6.0L should power it up. They think it is the cable.
Thanks
