I have a NBS 2007 1500 with a 6.0 and today I went to connect my supechips cortex tuner for the first time and....nothing

i found out that theres a coincidence between my power point nearest to the driver not working and the diag.port not working. apparently they share a fuse somewhere. WHERE IS THE FUSE? I have checked every flippin fuse in the whole truck in the cab and under the hood. I am frustrated. Please help. Thanks!

 

its under the hood
use a test light to check them
I think its a 15 amp in the bottom right hand corner area if your looking at it from the side of the truck.....can't say for sure though
