Haltech Nexus R5 VCU & Nissan Sentra SE-R | Nissan Sentra Spec V 2004-2006 Plug 'n' Play Adapter Harness Kit (HT-651246)

The final SE-R SR20DE gets standalone ECU support through a harness built specifically for this fitment.

The Nissan Sentra SE-R SR20DE has real tuning potential, and the factory ECU is the main thing standing between where it is and where it could be. 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.
