Frequently Asked Questions (FAQ)

Why is my C7 engine experiencing intermittent signal loss?

Intermittent signals are commonly caused by a worn 381-2499 harness. Over time, engine vibration causes the internal copper to break or connectors to loosen. Replacing the loom with a brand new 3812499 restores ECM communication immediately.
