It's best to actually test the wiring with a volt meter to determine if it's 12 VDC or 120 VAC.
Every unit but one that I have owned had SO cord running to the slide for 120v via the scissors hanger. My current Flagstaff is that way and it is in split loom!
To the OP... you are going to have to test them or have someone with knowledge test them for you.
Without actually being there, we are only guessing what may be in your wiring box and that's not a good thing when working with electricity.
