Nissan 370Z 2009-2018 Haltech Nexus Wiring Harness (BF29171)

The 370Z VQ37VHR is one of the most tuneable naturally aspirated V6 platforms in the Nissan lineup, and it responds well to proper standalone ECU management.

The Nissan 370Z VQ37VHR 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.
