84 Vette coupe, anyone know where online wiring diagrams can be had? My engine sensors' connectors - some are missing and I don't know which color or which side is the knock sensor, fan switch sensor or what.

I don't know where you can get them for free, but a book is available to purchase from Bentley Publishers at http://www.bentleupublishers.com. I know how much fun wiring can be.......anyway, good luck on your project!
