Late-model NSX C32B production is limited, and standalone ECU support for it is rarer still. This harness addresses that properly.
The 2005 Acura NSX C32B is a platform the tuning community has respected for decades, and standalone engine management is how you treat it with equal respect. The Tuned By Shawn 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.
