That's actually one of the harnesses I'm looking at and one of the devices I'm looking to power is an amateur radio. With a test light I can locate constant and switched power, but the (4) 30A pins appears to be dead under all conditions. Is there any way to make them hot, preferably as RAP, or are they useless without the switch bank? Just trying to avoid running wire through the firewall if I have all the power I'd need right there.

Is it possible to use the 30A terminals on the upfitter block in the driver side footwell if you don't have the switches, or is the necessary wiring simply not there? I have a 2016 Silverado LTZ, I"m looking to add some accessories inside the cab and thought I may be able to easily pull accessory or RAP from this location.
