This is a double post ! It looks like the same user but did not check.
Yup, same user.
There are already some replies to the original thread, but it was never answered by the original poster.

Is there a users manual for the board you are trying to wire ? That picture is not helpful.

Torch up - goes to input on BOB ( usually 12 )
Torch down - goes to input on BOB ( usually 10 )
ArcOK - goes to input on BOB (usually 11 )

If your plasma does not have the connector for torch on and a voltage divider, please ask someone else who is qualified to wire that.
That is very dangerous !!!
