Balboa spa circuit board

[kpinpoway]

So when connecting the control panel to the circuit board of a spa does j1 or j2 matter? I think its a master spa part. S/n 52757***200304110140
Board mas470 master spa le m7.

I can't find anything that shows the installation of that board.
Was there any instructions included with the board? If so, can you post them?
