I'm trying to install LED OCD on top of the Total Lightshow in my non-LED version of Metallica. I'm coming out of the driver, into the OCD board, then into the Lightshow board. It seems to be working, but I don't have the matrix terminator boards installed. All the lamps went on all at once when I left them in the driver board and they won't fit anywhere else. Do I need these boards or are they for newer LED runs of Metallica?
Thanks.
