Instrument Cluster Wiring Diagram
 

Everyone seems to ask about this, so I made a simplified diagram from the factory wiring diagram. Scanning the factory diagram is a no go since it unfolds to about 11x28, and with all the lines, would be a mess.
Here is my trial run for the 1976 year. Let me know if it makes sense or any other comments. If people like it, I will do everything from 1973-82.

nice, makes lots of sense. got one for 86?

Re: Instrument Cluster Wiring Diagram
 

Sorry, my manuals stop at 83.
I will modify the format a little of my diagrams a little after looking at the wiring harnesses on my 77 and 79 parts truck.

I know this is an old post but any chance you can get the "81-87" pages scan or a bit better in quality? I zoom in and it gets pixelized. I appreciate yoiu putting these up. I can look them up also if you let me know where you got them. Thanks.
