This is a complete new harness however, due to the fact that some connectors and grommets are made solely for Nissan, we require a core harness. If a core cannot be provided, we will supply one at extra cost. While this is a plug and play item, expert installation is required since it will require changing Motec firmware wiring assignments to match the supplied base map as well as possible retuning due to additional sensors.

Harness is provided with a complete full color PDF diagram of all wiring connections and a base map with firmware of choice with all connections populated.

  • Does not include Knock sensor harness but connects directly to OEM
  • Does not include primary injector harness but connects directly to OEM
  • 12-Injector harness sold separate. Engine harness has connector ready with secondary injectors wired behind intake manifold, not routing through firewall needed
  • Motec ECU sold separately

This is a custom-made item. Turn-around time is 2-3 weeks. We do not offer "mil-spec" finishing. All of our harnesses are finished to OEM specs using OEM routing techniques and the highest quality OEM covering materials. We guarantee all of our products are free of manufacturing defects and have tested them for years.
