For SNES -- This RF switch connects to the wide, rectangular Multi-Out port on the back of the SNES console, not the small round RF out port that has a single pin hole in it.
Also for Gamecube and N64 -- they all use the same wide, rectangular connector on the back of the console that looks somewhat like a large USB port.
If your TV is AV input-capable (has the red-white-yellow AV input jacks) you should use our N64/SNES/Gamecube AV cable for best signal quality instead of the RF switch.
