TSCN Black 14-Pin 2.8mm Sealed Connector – TS30427-14P-21-1 (APTIV 54201432 RP1226) for Automotive Diagnostic & Wiring Harness Applications

The TSCN TS30427-14P-21-1 is a robust 14-pin female sealed crimp housing connector engineered for reliable performance in automotive diagnostic systems and sealed wire harness assemblies. Designed as a direct replacement for APTIV (formerly Delphi) part number 54201432, this connector is part of the RP1226 diagnostic harness series, commonly used in OBD-II interfaces, engine control modules, and sensor networks across passenger cars, commercial vehicles, yachts, and off-road UTVs.

Featuring a 2.8mm contact pitch and sealed construction, this connector ensures protection against moisture, dust, and vibration—critical for under-hood and chassis-mounted applications. As the female counterpart to mating housing TS30427-14P-11-1, it delivers secure, long-lasting connectivity in harsh automotive environments.
