Haltech Nexus S3 - Haltech Nexus Plug-and-Play Harness Support
The Haltech Nexus S3 (Haltech Nexus Series) is engineered for modern performance and motorsports projects, and Boomslang supports Nexus installations with vehicle-specific plug-and-play (PNP) harnesses that deliver clean integration and reduced installation time. This approach preserves your factory harness, improves serviceability, and helps ensure consistent results for race teams, tuners, and serious performance builds.
Boomslang Haltech Nexus harnesses allow the ECU to provide full engine control. In select applications, the factory ECU may remain connected in parallel for OEM CAN bus communication or automatic transmission control. Certain BMW, Dodge, 1996+ Ford, Hyundai, and Kia applications require Haltech coil drivers to be plugged into the harness.
