Can anyone help me with the application for this wiring harness? It has a plug for a voltage regulator (I'm quite certain that's what it is) and a fusable link, among other plugs, eyes, etc.
The original box has a stick on envelope where the original invoice was in at one time, and it has on it '1776-1976 American Bicentennial' on it, which narrows down the years to 76 or earlier.
Any help in identifying the application would be appreciated.

I have looked thru my factory parts books, but so far, cannot find it.

Thanks,
