I just tried swapping the 2-pin cables from left to right side. It was a very tight fit, with the cables barely making it from side to side under the carpet. So now the left side has the 2-pin (purple wires into factory purple/black plug socket)) and the right side has 2-pin (green wires into unused plug) plugged in. This now enables the right door tweeter and the mic. But, the left door tweeter is not working. All the other 5 newly enabled speakers have output
I ended up tapping a signal from the left pillar speaker and running that to the purple/black left door tweeter wire. Used a 4.7uF electrolytic capacitor in parallel to the tweeter as a crude high pass filter. (Not sure what values the capacitors are in the box the cable connects to). The left door tweeter is also working now
