The wiring for the rear differential temperature sender on the Subaru WRX STI can sometimes get damaged or corroded. This repair harness is an affordable solution, especially compared to replacing the whole rear wiring harness.
Includes a butt connector for crimp-connecting to the existing wiring harness.
If you need the sensor itself, we stock that, HERE.
Fits all 2015-2021 Subaru WRX STI.
