Best fit
- Your vehicle uses a supported existing harness and you've confirmed Elite or Nexus ECU fitment.
- You want to review wiring scope, ECU selection, and your tuning plan together before you order.
Choose this instead
- Choose a universal wire-in harness if your wiring needs to be custom-built around the car instead of following a verified factory wiring plan.
Application notes

- Intended for sanctioned off-road and competition vehicles that aren't emissions-controlled. You and your installer are responsible for compliance with applicable laws and regulations.
