Norcold power boards and optical boards do not come with installation instructions, however, they aren't needed. The best practice is to take a picture of the Norcold board before removing any wires. This way, if you have any questions about what goes where, you can reference your photo. The color schematic of the wires going to the board will be different for each coach/ RV, so don't make any decisions based on color alone.
