Pretty much. Strip some of the wire wrap it around the bike spoke. Make sure if it's copper wire to have the bike spoke far enough out of the water so the wire doesn't make contact with the water. Wrap it with electrical tape then run the other end of the wire to a copper pipe in the basement. Sand the pipe a little so the wire makes good contact with the pipe. Wrap a stripped section of the wire around the pipe a few times and tape it on. Fyi it cost me like 2 bucks to make my probe.
