Newer sockets usually have the two sides connected by a jumper wire. Older ones may not be connected. ODNO makes use of the second output by wiring one to one side of the socket or to one pin on the end of a lamp, and one output to the other side of the socket or the other pin on the lamp. PLL lamps are essentially a long lamp, bent into a U shape. One outer the nearest inner pin are the same as one end of a standard linear lamp. The other outer pin and the one next to it, are the other end of the lamp.

If the socket is already connected by a jumper, you have to cut that.
Here is the diagram, from one of the original articles, that helped me figure out how to wire things.

One note. Though I did experiment with ODNO in the past, and it works, I've come to prefer two T5NO lamps over my tanks.
