Nexus Power for the 80 Series: Adaptor Harness for Toyota 1FZ-FE
Step into the future of engine management with the Haltech Nexus S3 Plug ‘n’ Play Adapter Harness for the Toyota LandCruiser 80 Series (1FZ-FE). This harness is the key to installing the cutting-edge Nexus S3 ECU into your classic Cruiser. The Nexus S3 combines an ECU, Wideband Controller, Power Distribution Module (PDM), and Data Logger into one unit. This harness connects that powerhouse directly to your factory wiring loom, supporting MY95-97 manual transmission models.
Integrated Control
By pairing this harness with a Nexus S3 (sold separately), you gain control over the 1FZ-FE’s fueling and ignition with unprecedented precision. The harness supports the factory sub-tank system and idle control (via the Nexus S3’s advanced stepper control). It allows for the deletion of the MAF sensor in favor of a MAP/Air Temp setup. The auxiliary I/O breakout makes it simple to add high-tech sensors for off-road data logging or engine protection. This is the ultimate wiring interface for the serious LandCruiser enthusiast.
