It seems to depict the data port as a Molex MicroFit TPA connector. If so, and if both ends of the cable you require are the same, then an off-the-shelf cable assembly such as the Molex 2147551043 would fit the bill:
Thank you, that solves part of my problem. My next question would be if anyone has the pin-out for the data wire as it links to the programming software, so I would assume it needs to go to a USB or serial connector.
