Where's my flasher relay ?!

I intend to use LED turn signals on my '87 Radian build.




I used the search and read a few threads about which flasher unit to use to make the LED's work. Stopped by Pep Boys today and realized I didn't know if I needed a two prong or three prong flasher.
Tried to find the flasher on the bike and I'm stumped. Consulted two manuals I have and neither is clear.
Which of these is my flasher relay? I don't see how to plug in the traditional style flasher relay, so how do I make the LED signals work?

On backbone, just above carbs.


Just behind the coils, underneath the backbone, and above the engine.

 

Nabbed these pics from ebay. Is this the same thing as the one with the blue connector that I have pictured?




If not, where the heck is the thing?

 

1st Pic is the self cancelling unit, Flasher relay on mine is under backbone in similar position to your blue unit, but connections on mine look different to the last pic you have shown.

hope this helps.
