Haltech Nexus T2 ECU & Toyota 4Runner 5VZ-FE | Toyota Tacoma 5VZ-FE 1995-1997 Plug 'n' Play Adapter Harness Kit (HT-650902)

The 5VZ-FE V6 has more in it than the factory ECU ever let you find out.

The Toyota 4Runner 5VZ-FE is a capable platform with a loyal following, but factory engine management puts a ceiling on what's possible. The Tuned By Shawn PNP Wiring Harness Kit for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.

Advantages

• Throttle response that's immediate and proportional to input
• Fuel delivery that stays accurate across load and temperature changes
• Engine behavior calibrated to your actual modifications, not Toyota's averaged factory map
• Consistent power delivery that doesn't change with heat soak
• A foundation for builds the factory ECU simply can't support

Features

• Plug-and-play fitment for 1995-1997 Toyota 4Runner 5VZ-FE, manual transmission
• Paired with the Haltech Nexus T2 ECU (HT-211000)
• No cutting or splicing of factory wiring
• OEM-quality connectors, USA-built by Boomslang Fabrication
• Fully reversible, factory harness preserved
• For competition and off-road use

The Details

Built specifically for this vehicle's connector layout with OEM-spec connectors and correct wire gauge throughout. Your factory harness stays completely untouched and the car can return to stock at any time. The Haltech Nexus takes full engine control once installed, giving your tuner a clean vehicle-specific foundation to build a proper map from.
