When given power do these default to on, off, or their previous state?

They default to on, wire them to a permanent live, and turn them on and off at will

My cigarette lighter has three wires how do i wire it the usb has two

You will find one being the earth and one will be 12v the third will be a very low voltage wire which is usually used for a small light to light up the socket.

Which cable is suitable to extend the length of this? Is there a certain gauge?

Hello, thank you very much for contacting us. This cable is 23.6in/60cm,10Afuse.

is the red wire live and black neutral ? thanks

I used red for positive (live) and black for earth. Also used a fuse on the red wire between battery and USB socket. Works fine for me.
