Start at the brake light socket. Whi/tan wire is the brake light feed from the brake stop lamp switch. Check for battery voltage with brake stop lamp switch pressed down. You should read battery voltage. If no voltage move to the brake stop lamp switch.

The switch has pink/dk blu wire feed from the fuse and the whi/tan wire going to the brake lamps. Test for power at the pink/dk blu wire. You should have battery voltage at that wire. If you have battery voltage, press the brake pedal and test for battery voltage at the whi/tan wire leaving the switch. If you have voltage at that wire at the switch, you have a break in that wire going to the brake lamps. If you have no voltage at that wire, you have a bad brake lamp switch.

If you have no battery voltage at the pink/dk blu wire going into the brake stop lamp switch, you have to move to the fuse and test there. You should have battery voltage on both sides of the fuse. If you have voltage on both sides, you have a break in the pink/dk blu wire going from the fuse to the brake stop lamp switch.

No power at the fuse #22 15amp. you have a problem in the power distribution center.

According to this picture it shows fuse number 22 to be a 20A. I read on another link that it may b fuse #25? Which is that is the case, that is a 15A? Does anyone know how the pink/dark blue that runs from the brake lamp switch to the fuse box connects at the box?
