The final tC 2AR-FE is a solid naturally aspirated four-cylinder, and this harness puts standalone ECU support within reach.
The Scion tC 2AR-FE is a well-sorted platform with a loyal following, but the factory ECU limits what's accessible for serious modifications. The Tuned By Shawn PNP Wiring Harness Kit for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.

- Throttle response that's crisp and direct, not filtered through conservative factory logic
