You will need two Energy Links, these convert the power to work with the quarry instead of electrical engines, place one on either side of the quarry and then attach a pipe to the top of the quarry and you should be up and running.

That's how I'm running things and it's going fine now, seems in the latest versions without forestry we lost the electrical engines so need to now use Energy Link :)
