in the under hood fuse box the fuse called stop lp a 25 amp fuse shows NO volts on either side of that fuse testing it in place through the little openings in the tops of that fuse ?

The 25 amp fuse under the hood has power on both sides

does the orange wire at the brake switch show 12 volts ?

No power at the brake switch or the 15 amp vehicle stop fuse
Expert:  Gary replied 1 year ago.

the 15 amp fuse will NOT get volts until the brake switch sends power to it

since the orange wire at the brake light switch shows NO power but the fuse in the under hood fuse box the 25 amp fuse shows volts the issue is power from that 25 amp fuse is not making it to the orange wire at the brake light switch

that orange wire is either damaged under the fuse box or the connection under the fuse box is bad or the orange wire is bad or broken under the dash near the brake switch

once 12 volts is restored to that orange wire at the brake light switch everything should work fine
