They've now found the identified the fix, which you can either re-wire yourself, or send the harness back to Technic to be corrected free of charge. Looks like folks have had their bass back once this is done. 
Here is the post in question, as well as the original thread:

Deepest thanks to the good folks who figured this out!!!
I just made the suggested "fix" to my harness. Can't test it yet as my M2 is still on a ship, currently docked in Panama.
Note that it is possible to make the alteration without cutting/splicing wires. Refer to the later replies (starting with Reply #93) in this thread:

Instead of using a jeweler's screwdriver to release the retainer clips for the contact pins, I used a paper clip (as recommended by another contributor to that thread). You just slide the end of the paper clip into the little hole next to the pin, apply lateral pressure, and the tiny spring clip should release, allowing you to pull the wire free. If it doesn't work, then try inserting the paper clip into the little hole on the opposite side of the pin (there are holes on both sides).
Note that the pins are not necessarily inserted into the connector in the same orientation, so you may need to "probe" the inward hole (i.e., the one toward the center of the connector) for one wire, and the outward hole (i.e., the one toward the edge of the connector) for the other, which was the case for me.
Before re-inserting the wires, reversing their positions, of course, I used a tiny screw driver to bend out the little spring clip on each connector - they'd flattened out a little during the extraction procedure. Good luck! -scr
