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

  • Not sure this is the right part? Send us your vehicle, engine package, wiring approach, sensor set, and CAN layout and we'll help you choose.
  • 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.
