The Haltech Nexus S3 Plug and Play Adapter Harness is engineered specifically for Australian-delivered Subaru WRX STI models from 2011 to 2019. This precision-built wiring solution eliminates the need for cutting, splicing or modifying the factory loom, allowing direct integration between the Nexus S3 ECU and your STI's existing electrical system. Factory-style connectors ensure reliable connections while maintaining the integrity of the original harness. Purpose-designed for ADM vehicles, this adapter streamlines professional installations and reduces fitment time in workshop environments.
