First, connect all of the pieces for each light before laying them out. Then lay out the lights as you would like them, without staking them into the ground. Next, you will need to layout the cable and connect the light to the cable with the connector cap, so that the cap punctures the cable and makes contact with the wire. Finally, dig a narrow trench along the cable path, connect the cable to the power pack and then plug the power pack into the GFCI or outlet.
