It's complicated. The tweeters have 4 wires at each connector. 2 wires carry the audio signal into the dash speakers, and 2 are outputs (pass-through) for the midrange. D39 and D66 in your diagram represent the tweeter connectors.

Each speaker has its own high-pass filter (capacitor) onboard, and the speakers are wired in parallel.

If you want to use the factory wiring, it's best to pull the stereo signal from the existing amplifier harness. On H14, use 3/9 (left input signal) and 4/10 (right input signal). 1/5 and 2/6 will be the outputs to your door woofers. You'll want to run speaker wire to the dash for your mids and highs. H13 is useful for getting the remote turn-on (its on the previous page of the manual).
