Broken wire leading to stop light switch

[AzTank]

ANOTHER UPDATE> checked all the harness all the way back to the taillights. no breaks in the wiring. I did find however just by accident, the reverse lights will turn on briefly as the transmission either go INTO and OUT OF reverse. If i hold the shift lever in between, the reverse lights light up bright. still no break lights at all. looks like my problem is somewhere in the column area.

actually that would be a defective external park/neutral safety switch on the tranny.
