The diagram you have is likely the diagram for the green board.

OK. is the difference between red and green boards only in the position of the elements? are the elements themselves the same for them?

The circuits are similar but the circuit board designations are different. If you had no clue as to the circuit being used, the green diagram would be helpful but don't expect a perfect match.

PapaZBill will help with specifics. He has the best access to Kicker documentation.
