Do you have the original point ignition or do you have some kind of module and solid state setup. The way you describe 2 wires on the negative terminal and a direct connection to ground on the positive terminal sounds like an aftermarket ignition of some kind. I can't really comment on solid state wiring since that depends on the setup used. Whatever the module or other solid state components would require probably differs between units and I am not too familiar with what is available.

For a non overdrive car with a set of ordinary points and a condenser located inside the dist which would be the standard configuration there would only be 2 wires involved. Power to the coil would be supplied by the wire from ign switch connected to the negative coil terminal and the points would interrupt the flow by their opening and closing connecting the positive coil terminal to ground thru the body of the distributor. If the car has an OD there would be a third wire also connected to the positive terminal which would momentarily go to ground and briefly stop the spark when kickdown is engaged.
