Lotus Elise | Lotus Exige 2006-2011 Haltech Nexus Wiring Harness (BF29166)

The Elise is already one of the purest driving experiences available, and standalone ECU management is how you make sure the engine is calibrated to match.

The Lotus Elise Toyota 1ZR-FE runs a Toyota-sourced engine in one of the lightest, most responsive chassis built for road use, and every calibration improvement shows up immediately in how the car drives. The Boomslang PNP Wiring Harness 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.
