Hello all.

My joe jedi board arrived this morning and..I'm not sure what the previous owner was doing.

I can't figure out based on existing diagrams floating around what to do here.

Specifically...

What is the power (+ and -) connection here?
Which is the speaker connection?
Which is the power switch connector?

I'm nominally going to just use this as a sound board and not use it for driving a LED at all (maybe an accent down the road) but for now just use it in tandum with a resitor driven setup and if need be down the road the more advanced wiring diagram using a DPDT and all.

Here are the pics:
