The Haltech Nexus S2 and S3 are the successors to the Elite 1500 and 2500. They keep the two-connector Elite layout and add the processing power of the Nexus platform.

Buy either ECU on its own, with a plug and pin set, or with a 2.5 m (8 ft) universal wire-in harness. The collection also has the universal harness alone, separate plug and pin sets, and LSU 4.9 and NTK wideband hardware packs.
