Here's the entire schematic from
the WDS, FWIW.
Fuse 14 is
all the brake lights, so not much help there.
You're sure you aren't plugged into the "mystery connector"?
When I replaced my cracked light, I noticed a similar connector hanging up there, but didn't investigate.
Assuming that's not the case, I would next check for voltage at pin 16 on connector X12 of the Light Switch Cluster.
As for where that's at; I'll leave it as an exercise for the student.
