Rebel wire sells one like that. Though, I am not sure yet on it. The only problem with it is that you gotta buy the end to crimp onto it like alternator and what not. My teacher in the Chrysler Automotive Program recommended getting one through Year One instead of the generic 12,14, etc circuit kind. He said we can just alter it if I ever need to. Also, I think after u get all the odds and ends to do a wiring harness like that it becomes pretty expensive.
