With the CPC cable, you will only be using the DIV Input and DIV Output jacks.
The short cable goes to the DIV Input of the VIM module. The long cable will go to the Torch On/Off of the enclosure.
You will have another cable to connect DIV Output to the THC of the Enclosure box.
Once these are connected correctly, I suggest that you label the end of the cable with the label of the corresponding jack of the box or enclosure.
