Lawn irrigation wires and hookup?

My irrigation system stopped working, and I noticed these wires coming out of the system that obviously need to be connected to something. I also noticed this weird looking thing coming out of the conduit that is most likely where these need to go. My guess is I accidentally ripped the wires out with the garden hose. I posted the images below. Has anyone every seen anything like this? I'm fairly knowledgable about fixing things in the house, but I've never seen something like this.
