Thanks. The color code is standard, tons of them if you google RJ45 color code. Here's a link:
Ethernet Cable Colour code standards
Because this is not actual ethernet, the colors only matter to the degree that you want the connectors wired properly. Inside the controller, colors have no significance.
The Ethercon connector came with a little color coded diagram pasted on the inside. I just followed the diagram.
One more detail, the ethercon connector is a bit finicky when it comes to latching. If your panel mount receptacle and connectors do not align properly, the jack will not latch and you won't get a clean connection. Be sure to use a small file and de-burr the holes made both for the panel mount and for the screws so the two surfaces (connector and panel mount ring) and exactly parallel. I hope this is clear.
