OEM LS2 Wiring Harness

An original LS2 wiring harness can simplify a restoration or swap compared with building a wiring system from scratch. This harness retains the factory connectors and sensor connections needed for the LS2 engine management system, helping preserve the OEM-style electrical architecture.

The harness was removed from a running donor vehicle and inspected before shipping to help verify its overall condition.

Matched ECU Included

The included GM ECU is matched to the harness package, giving buyers a more complete starting point for an LS2-powered project. Because C6 Corvette electronics can vary by model year, transmission, and configuration, always verify the ECM type, connector configuration, transmission application, and calibration requirements before ordering.

This C6 Corvette LS2 wiring harness and ECU package is suited to compatible factory replacements, restoration projects, and custom LS2 swaps where retaining OEM-style engine management is important.

• Factory connector inspection

Transmission and option differences can also affect harness compatibility. Verify the exact year, transmission, ECM, and harness configuration before purchasing.
