Hey Paul,
This is a little shout out to Paul Whittle and his reverse engineered Magnum Opus control board.
We received our new board, followed your supper easy instructions removing the old board to install your plug and play new board in my Magnum Opus, it's now working again in less than 15 minutes.
Thank You Paul Whittle for doing such a great job reengineering the Magnum Opus control board and making it so user friendly fitting perfectly where the original board was placed hidden in the back of the toilet.
