This Muzzys 2-wire pigtail connector is exactly what you need when those factory engine connectors start failing! It's made in the USA using the same OEM-quality Delphi/Packard connectors, terminals, and seals as the original equipment. The metal hoop design provides a much more secure connection than the plastic locks that often get brittle and break over time. This little repair harness works with so many applications - Variable Geometry Turbo (VGT) solenoids, Injection Pressure Regulator (IPR) valves, HEUI A/B injectors, and valve cover gasket repairs across Ford Power Stroke engines (7.3L, 6.0L, 6.7L), Navistar engines, and GM Duramax 6.6L engines. The wiring uses the proper gauge high-temperature TXL wire that stands up to engine bay heat. Installation is straightforward if you're comfortable with automotive electrical work - just cut out the damaged connector and splice in this new one using the included high-quality nylon splices. Whether you're dealing with a check engine light caused by a faulty connector or doing preventative maintenance on an older diesel, having one of these pigtails on hand can save you from much more expensive repairs down the road.
