Does anyone have the pinout for the MC-DC3 remote connector?

Don't have the pin out, but it's the same remote used for years on Nikon DSLR bodies. Aftermarket units are dirt cheap.

Sorry, that is wrong. Nikon has used a ten-pin connector for years. The Z5 II uses TRRS headphone jack, which has three circuits. Only two are needed, and I need to know which two.

My misunderstanding. My response is right for a Z5 but incorrect for Z5II. And that is a 4 conductor phone plug instead of the more industry-standard 3 conductor plug other cameras use.
Odds are the lowest (outermost) conductor of the barrel is the common like any A/V connector and then you guess which of the 3 that remain is release. But I suspect it is a 2-stage momentary contact switch (electrically 2-pole 1-throw in a sequence) so 3 of the contacts are in play. That to allow for the half-press focus and exposure lock like my remote cord does.

Sources appear to agree. I see common is not on the sleeve as I expected but the 2nd ring. Release is tip, focus lock is 1st ring. And there is a 22 ohm resister in series for protection. I might have followed my high school electronics teacher's advice and use a signal diode in series there. That is what I did when wiring reset buttons into Commodore computers for my friends.
