I opened up the panels today and found the 6-ping harness just sitting there ready for use. I believe my VIN 54797 was manu'd during a period in 2014 when Tesla was including the harness for the Conti ECU, but still installing the Balong ECU in the rear. Not sure why they did this, perhaps to draw down on purchased Baolong ECUs? Anyway, I just plugged in the ECU I purchased from the SC, and this week will install the new sensors and change the Toolbox config to Continental 2, and disconnect the Baolong ECU.
