Haltech Nexus S3 ECU & Acura TL 2004-2005 Plug 'n' Play Adapter Harness Kit (HT-651544)

The TL J32A V6 is a capable engine in a well-sorted chassis, and standalone ECU management through the Haltech Nexus gives you access to what it can actually do.

The Acura TL J32A has real potential, and the factory ECU is the main thing standing between where it is and where it can go. 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.
