Look at the pic labeled "Option 2." The end with four leads (the resistor leads) is shown pointing up, and the two thicker leads are on the end that's pointing down. If you compare to the picture of a single LED/LDR package immediately below, and to the "Option 3" board layout pic, you should be able to figure it out. The trouble is that you can't see the LED leads through the package as it's drawn. Make sure you get the LED polarity right, and don't forget the jumper that's pictured to the left.

Good luck! The Neutron can be a bit of a hassle to build, but it's definitely worth it!
