Tiptank jettison was no where near the armament panel on CF T-33's... not sure about those anemically-powered US birds. :)
On the Canadian birds the armament panel is by the pilot's left hip on the side console, the tank jettison is a big button on the main instrument panel. It's mounted on the lower, fixed, portion just to the left of where the stick would be at full forward extension. Not much chance of confusing the two.
