Ok, my head hurts! I'm tired of trying to find what I need and only getting half the picture.
Well, they are wiring Diagrams after all. So your head will probably still hurt!

But both of those diagram sets are very well thought out.
Steve83 did a lot of work to his and has multiple years listed, and updated many of them with input from lots of members here.
The Seabiscuit Diagrams have been around for half of forever, and were updated a couple of years ago. They’re also pretty complete and work well.
Between them, and maybe even having a book or print those from the Internet, can usually get you where you need to go. Unfortunately for the traditional aftermarket books like Chiltons and Haynes, they didn’t always have corrected Diagrams.
And the 71s were completely wrong. Luckily the 72s were more accurate, but they use that strange format that was a transition between the old and the new.
I prefer the Seabiscuit and Steve83 drawings myself.
