Wiring Speaker Jack for EAS

[rugbyrat]

I'm working on an EAS helmet and I've decided to replace the original speaker connection on the circuit board with a 1/8" jack so I can plug in earbuds.  I can't read wiring diagrams, so can someone please help me read this? 

 

Here's the diagram that came with the jack, and a picture of the speaker connector on the board.  Where do I put the ground and where do I put the speaker wires?  I only need mono sound, as I'll be using 2 boards to get stereo.  Thanks in advance!

I'm not sure what the lower half of the diagram is supposed to look like, but the upper looks like a cross section of the socket you put the jack into, and if you look at the jack it's easy to see what goes where.

 

So 4/5 is right, 3/2 is ground and 1 is left. At least that's how I imagine it goes.
