Correct placement of 67 Barracuda instrument cluster wire.

So, I am currently encountering the joys of replacing my instrument cluster bezel in my 67 Plymouth Barracuda.
I've been very careful to label everything and followed a "How To" Sticky on the process.
But, my middle name is "Murphy", after Murphy's Law.
I bought a new Bezel for just under $700, and am not sure if it is top of the line, as I've had to do some adjusting.
I just got done repairing the little plastic post that holds the HVAC control wire and was ready to start reinstalling.....and I look to my left.....

..and see that one of the wires to the to the Cluster lights has popped out of the circular connector.
See the picture; it's the dark blue wire loose above, and I'm sure it belongs either to the left or right of the lone connector with empty spaces on either side. But, which one?
Anyone got the past experience to know, or a diagram so I'm sure to get it in the right slot?

I will also move the circular connector close enough to see if there is a pin that needs a wire connector for it.
