Haltech Nexus S3 ECU & Toyota 4Runner 5VZ-FE | Toyota Tacoma 5VZ-FE 1995-1997 Plug 'n' Play Adapter Harness Kit (HT-650958)

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
