I need help with 4:1 Compressor

[Ariosto]

Hi everyone,
I need to know where to solder the "G", "L", "I" and "O" cables in the Four One Compressor. I can easily assume that they are Ground, Input and Output, but still not sure about "L" (Line?). The PDF does not help too much, or my knowledge is insufficient. Please write me to:
cristian_fe@yahoo.it
Thanks in advance! Greetings from Germany!

 L is the LED wire that goes to your 3pdt. Here's the link to the 1590G build guide. Page  19.  Your assumption on the other pads is right.  Just look at the guide and it will show you how to wire it.
