Is the small hose a vacuum line or a coolant hose? If it’s a coolant hose it’s probably running to your idle air control valve (near the throttle body). Disconnecting the IAC hose may mess with your idle smoothness.

If you live in a cold climate, the throttle plate can freeze without coolant running to it.

Will it hurt my 94 ford f150 5.8L 351W motor if I connect the small hose that was once clamped to the throttle body to the small hose that was clamped to the copper or metal line underneath the throttle body. Apparently the hoses had never been removed from the metal lines before I bought this truck. I discovered that both the top and bottom metal lines were rusted when I removed those small rubber hoses from throttle body to clean the the TB. From what I’ve read, correct me if I’m wrong, it should not hurt my vehicle my truck if I connect both of the small hoses together because the bottom hose was connected to the input line whereas the top metal line was the output line which goes back to the radiator, right?
