Haltech Nexus S3 ECU & Chevrolet Camaro L99 2010-2015 Haltech Nexus | Rebel LS Wiring Harness Plug 'n' Play Adapter Harness Kit (HT-651498)

The Camaro L99 has more in it than the factory ECU was ever going to release.

The Chevrolet Camaro L99 is a capable platform, but factory engine management puts a ceiling on what's possible. The Tuned By Shawn PNP Wiring Harness Kit for the Haltech Nexus / Rebel LS connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus / Rebel LS full standalone engine control. No cutting, no splicing, fully reversible.

• Fuel and ignition timing calibrated precisely to your actual setup
• Consistent power delivery that doesn't change with heat or temperature
• Idle stability that's locked in regardless of ambient temperature
• A tune that actually reflects your build and your intentions for the car
