Yeah, the GVDCVG is ground, voltage, data, and clock. My board is going to sit between this ribbon cable and the part that normally connects there.
You do make a good point though. I was hoping for an elegant solution where this ribbon cable was the only connected component, but there's a large exposed voltage testpoint exposed nearby. It's 1.5mm wide and 3mm from the board edge. I bet I can find a miniature allegator clip or some other way to connect to that.
I tell people to take apart an ancient junk switching supply wall wart with a hammer and unwrap a winding from the transformer inside. That gives easy access to a small bit of enameled copper wire. They will need to be extreme about scraping the enamel to get to the copper. It is also a good idea to use a lighter to heat the enamel and scrape some more. Then they can wrap the exposed copper part around something like that transistor lead a dozen or more times like it is an old wire wrap job. If you can locate two such locations where a lead with an air gap exists, it is possible to make that connection.
