Default Help for 1975 200 4x4 Ingition wiring

I have a 1975 200 4x4 with the gold box on the firewall. The truck is a 392, 4speed.

First off, can someone post or tell me where to find a wiring schematic for the ignition?

Second, there is a small box of some sort on the firewall that a white wire from the ignition module goes to, and also has a vacuum hose going to it from the carburetor. I'd like to know what that box is and what it does. It is just to the passenger side of the ignition module on the firewall. I'm thinking that it must have something to do with timing since it has vacuum and hooks to the ignition module, but I'm not sure. None of the wiring diagrams I've found so far show that white wire that goes to it from the module. If this unknown box goes bad will it cause issues with cold starts?
