Does polarity matter for the anti-lock braking system wheel speed sensor on a Mazda RX-7 FD?

Data is available for the earlier FC3S (S4 and S5) RX-7. On those models, the wheel speed sensors are magnetic reluctor passive sensors set up for a magnetic falling edge trigger, and specific positive (+) and negative (-) wiring polarities are defined for each wheel ¹. Because magnetic reluctor sensors rely on polarity to generate the correct waveform (such as a falling edge trigger), wiring them backward typically results in an inverted signal that the ABS computer or ECU cannot read properly.

While it is highly likely the FD uses a similar reluctor-style sensor where polarity would matter, I do not have the specific sensor data or wiring diagrams for the FD chassis to verify.

Is there another system on your FD you are currently troubleshooting?
