Dana proved here that the Start and I2 terminals are not connected to each other, at least in the dash mounted switches used through 1969.
Those terminals are independently connected to the B terminal when the key is in Start position.
So have I. ALSO BEAR IN MIND that in the newer diagrams in service manuals such as 73/ 4/ 5 the ignition switch IS NOT DRAWN correctly. The newer diagrams would lead you to believe that the start and bypass are interconnected.
