Just bought my Titan. Awesome truck. I hooked up my trailer but there is no power to the 12 Volt power lead in the 7 pole connector on the truck. I may have shorted it testing the braking controller I installed. I can’t find an obvious fuse description for this lead either on the dashboard or under the hood. Does anyone know where the fuse is for the 12 Volt power lead on the trailer plug? Thanks in advance for the help.
