I'm not familiar with the wiring of vehicles as new as your column. The piece that is missing from your description is the flasher unit.

Is there a flasher mounted on the column? My bet is no. I suspect something in that BCM box provided the 'flash' and you may need to figure out how to add that with those additional wires.

I sit at a computer all day to make a living, but I've mostly refused to work on computer controlled cars!

It's true. I really don't do anything but browse the Internet looking for trouble...
