This is the blue E40 ECM connector for the LS2. It is often missing from the engine harness because it is integrated into the body harness. I have a large quantity of these available. The connector(s) and wiring is all brand new using the same items as the original harness.
This is available as pictured (2ft length) for $50.00.
This is also available as a 2ft pigtail with the accelerator pedal connector (specify length) and diagnostic connector (specify length) installed. This configuration will be $75.00.
Shipping will be $5.00.
Location is Erie, Pennsylvania.
