Spirit Lance...help!

I know you need to activate 3 qactuars but I can't seem to find the last one. I did the one near the save point near Guadosalam and I forget where I activated the other one...but it's really annoying running around , getting into battles every few seconds, getting struck by thunder when I least expect it, like right after the menu screen disappears, and having no clue where Im supoposed to go. does anybody know where the other two are? :( :confused:

One of them is somewhere in the South area on the right side, just below the chest containing the Water Ball for Wakka. (Not much help unless you have found that already :) ). I'll tell you where the others are when I remember.
