A compatible sensor is sold separately.\u003cbr\u003e• Compatible 12-pin and 16-pin mating connectors are required to complete the vehicle-side power, starter, alternator, CAN, fuel-pump, fan, and auxiliary-I\/O wiring.\u003cbr\u003e• An application-appropriate alternator adapter cable is required and sold separately.\u003cbr\u003e• Confirm the alternator type before selecting an adapter.\u003cbr\u003e• Harness revisions use different 12-pin and 16-pin connector assignments. Always follow the printed wire labels and the wiring diagram corresponding to the supplied harness revision.\u003cbr\u003e• Early unmarked REV1 harnesses use mirrored connector pinouts compared with later revisions.\u003cbr\u003e• Fuel-pump, cooling-fan, wheel-speed, flex-fuel, and other vehicle-side functions require final wiring through the auxiliary connector.\u003cbr\u003e• This harness is intended for custom installations and does not constitute a complete plug-in replacement for the original Toyota vehicle wiring harness.\u003cbr\u003e• Final ECU configuration, trigger setup, injector data, ignition settings, sensor calibration, VVT-i control, idle control, and output assignment must be completed in MTune for the specific engine and vehicle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEmissions and Competition-Use Notice\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eUnless specifically identified as emissions-legal for the applicable vehicle and application, this product is intended for sanctioned competition, off-road, or other non-emissions-controlled use.
