Downloaded and printed the latest Dynon install manuals. Went through the diagrams and removed the wires from the harness that I don't need. Checked all of the pins and labled wires. Grouped them based on where they need to go. Laid out the wires to see different routing options. One thing I am going to do is have one port mounted in the sub panel for software updates, I will have to make up different cables depending on which box I am updating.
