Nissan Maxima | Nissan 300ZX Turbo 1995-1999 Haltech Nexus Wiring Harness (BF29092)

The VQ30DE Maxima is an underrated naturally aspirated V6 with real potential when the ECU limitations are removed.

The Nissan Maxima VQ30DE has real tuning potential, and the factory ECU is the main thing standing between where it is and where it could be. The Boomslang PNP Wiring Harness 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.
