The harness for the fuel injectors run through the valve cover and into this internal injector harness. One harness for each bank, two total.
We STRONGLY recommend replacing these harnesses whenever replacing the valve cover. Accordingly we also recommend replacing the valve cover gasket whenever installing new internal injector harnesses. Valve cover gasket kit available. We also stock the external harness pigtail if needed.
For 1999-2003 models.
