Brake lights don’t come on, I figured it out that the switch isn’t getting any power, where does the wiring harness get power

Have you checked the fuses?
Everything is all good fuses work and get power
So check the wiring from fuse box to the switch.
Does the truck have a brake light relay or is that on later models

Check this fuse again. Use a test light and make sure there's power at both of the fuse test terminals. Pull the fuse and examine the fuse legs and that fuse's socket for corrosion.
