Bad starter? That could be a possibility. Also, there may be a weak ground somewhere, that could cause it to do that.

Ignition switch at the base of the column bad, or in need of adjustment? You know the run part of the switch is good cause you jumped at the starter. And the car ran, but the start function is not

Just check the purple wire runs from the starter to the neutral safety and then ignition switch. Check that

Disconnet the clutch rod under under the brake booster. Check for power when you depress the clutch. Should be two screws holding the safety switch. Loosen and rotate until you have power in and out of the switch. Sometimes you can just bend the rod to get the adjustment.

Are you sure you bought a '75 and not a '74? That box sounds like the '74 only seatbelt interlock relay. The car won't start unless the seatbelts are buckled.
