Haltech Nexus S3 ECU & Scion xA | Scion xB 2006-2007 Plug 'n' Play Adapter Harness Kit (HT-651139)

The xA platform doesn't get a lot of standalone ECU attention, and that makes this harness more useful than most people realize.

The Scion xA 1NZ-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.

Advantages

• Throttle response that's crisp and direct, not filtered through conservative factory logic
• Fuel and ignition timing calibrated precisely to your actual setup
• Idle stability that's consistent regardless of temperature
• Engine behavior that reflects your modifications accurately
• A foundation your tuner can properly build from

Features

• Plug-and-play fitment for 2006-2007 Scion xA 1NZ-FE, manual transmission
• Compatible with Haltech Nexus R3, R5, S2, and S3 ECUs

The Details
