Toyota 8-Pin PDC Reversing Radar / Parking Sensor Wire Harness Connector – OEM 6189-1240 / 90980-12520 | Male & Female
The OEM 6189-1240 / 90980-12520 are 8-pin connectors used in Toyota Parking Distance Control (PDC) reversing radar sensor harnesses. The Sumitomo part number 6189-1240 and Toyota OEM cross-reference 90980-12520 (also listed as 6188-0779 / 90980-12519 for the mating connector) refer to the same connector family. The 8-pin configuration consolidates multiple PDC sensor circuits — power, ground, and individual sensor signals for up to four rear parking sensors — into a single connector. Available in Male and Female variants, bare or with 15cm pre-wired leads.

Frequently Asked Questions
Q: My Toyota PDC beeps continuously when reversing — is this the connector?
A: Continuous beeping on reverse (as if an obstacle is always detected) can be caused by a corroded PDC sensor signal pin that the ECU interprets as a constant obstacle detection signal. Replace the connector and clear the PDC fault before replacing the sensors ($30–60 each).
Q: Are terminals included?
A: Yes, terminals are included with all variants.
