There are quite a few ways to hit that harmonic.
2nd fret-6th fret stretch is the way I do it.
but you can also stretch from the 6th fret to the 11th fret, it's the same distance, so that might not be much help
there is another way that may be easier for you. Do you know about thumbing false harmonics?
Fret the 12th fret of G, then take your thumb and rest it at the end of your fretboard(if you have a 24 fret neck, if 22, then rest it a little bit past the 22nd) then take your index finger and pluck the string from behind your thumb, if you don't get a harmonic then just move your thumb around a little till you do.
basically you are thumbing the distance 12 frets away from where you are fretting, so you get a harmonic.
Now take this in context of the song.
hit the 6th fret of the A string then do the place your thumb, roughly around where your first pickup is, again experiment to find the harmonic node, but it is somewhere around there, if I knew what type of bass you had and it's measurements I could tell you exactly where, but I don't so just bear with me.
if you are confused, I'm sorry, it's kind of difficult to describe this technique without showing you a picture...I'll try and find a picture, but until then, try and make some sense out of my post and you'll have it.
