How did you make the change from a four-pin (external coil) distributor connector to a five-pin (internal coil) distributor connector?

There are two:
- CYPP: YEL (or ORG) to dist. connector pin 4, YEL from connector to ECU pin C4
- CYPM: BLK (or WHT) to dist. connector pin 5, BLK from connector to ECU pin C14

Yeah, I have or had the same problem, DTC 9 popping up. What I've done after scouring the FSM and internet:
On that page is a picture of a good and not-so-good sine wave. Quote:
- Checked the sensor resistance; slightly low at 340 Ω; spec is 350 - 700 Ω. Checked junkyard distributor and it measured 360 Ω so I left my old distributor in and got the CEL a few days later.
- Changed the brushes and diode pack in the alternator. There's a Civic TSB floating around in which Honda says dirty DC output will trigger a CYP CEL. Got a DTC 9 within a week.
- R&R'd the distributor and cleaned some minor corrosion off of the sensor.

KOER at idle ( 800RPM ) you should get about 0.7vac, 15Hz
KOER at 2500RPM you should get about 2vac, 21Hz
