I was wondering what year model engine harnesses will work with my Cobalt
Is it a 2.2L or 2.4L? If 2.2L without dual VVT then any 2007-2009 engine harness parts will work. Look out for California cars with their extra air injection/smog pump connections.
What parts of the engine harness do you need? You know there several sub assemblies that make up the engine bay electrical harnesses
