On the brake light switch connector the pink wire with a dark blue tracer is the feed from the fuse box, fuse # XXXXX a 20 amp fuse, which when the brakes are applied will feed power out the white wire with a tan tracer
Let me know if you have power at the pink/dark blue wire so we know which way to trace the system
The other thing to look at is the rear light assemblies, they get ground through the bolts that secure them to the body,be sure that the mounting bolts are tight and clean, and that no add on accessories like light cages are interfering with the ground
I hope that this helps
Let me know what you find and we can move onto more testing as needed
Whenever is convenient for you, I will be available most of the day tomorrow and after work on Monday
Just let me know what you find and we will know which way to go
The wire should go to fuse number 2 a 20 amp fuse in the fuse box
Is this the empty space?
Remove the glove box and there is an interior fuse box behind it
The fuse block module is mounted to a bracket on the dash panel, above the heater-A/C housing and behind the glove box. It has cavities for up to 20 blade-type fuses. A label on the heater-A/C housing beneath the fuse block module identifies the cavity assignments and fuse sizes. The fuse block module is accessed by removing the glove box.
