Dash cluster wiring question: blinker connection
 

Hello all,

My buddy and I have been working on a 1960 Chevy Apache for the last few month (take a look here: http://imgur.com/a/elQcV ) and we are almost done! Just the finishing touches are needed and this thing is a sweet Sunday driver. But we've run into a small mystery ...

Where does the blinker connection from the back of the dash cluster plug in?! Two blue wires run from the green blinker lights in the cluster into a white plug, where does it plug in?

Here's a link to the plug in question http://imgur.com/03kTj0S

I appreciate your help.
