I only have one for a 70 Chevelle not sure it will help on a 66. Don't know what Ray has available. As mentioned, the wiring diagram shows the connections. It does not show the physical layout so won't help much on how to route the wires. I can send the one I have if you're still interested. PM me with an email address I can send it to.
