If you are using single color LED strips, they usually come with leads and not a connector. If you have a connector, you can simply cut it off if you don't want to use it. If it is a multi-color strip, then you will need to use their controller which might require 120 VAC. I used the 12 volt TT source for my single color strips along with an infrared switch to control on/off and brightness. The switches are on Amazon. There are many threads on this forum with the links.
If you cut the strip to length and want to use the remaining strip, you will need to remove the coating to get to the connections. Amazon sells connectors that clamp on to the strip and make contact with the connections. Again, there are threads on this forum with all that "stuff". Good luck.
