To add a bit of clarity, the brake switch is being grounded through the taillight bulbs via the column connector.
The brake switch connects +BATT to the column where it passes through the turn signal switch and is routed out to the taillights. It is then grounded through the bulb.
Did the turn signals work before you replaced the harness? Do you have a multimeter (or ohmmeter) to check the wiring inside the column?
Edit: Out of curiousity, are you running LEDs or incandescant bulbs? How is the brightness of the dash indicator to the right vs the left?
