Hi Jay, yes the Grus is a nice solid mod isn't it. I'm not sure I follow you 100%, and apologies for my confusion and if this is not what you're asking - but if you can find one of these (uk ebay) https://www.ebay.co.uk/itm/133924234834, things might become easier. I have one of these but before it arrived I managed to get a reliable solder joint on one of those 16 pin usb-c male plug ( https://www.ebay.co.uk/itm/125074524290 ) . I didn't remove anything from the plug, just soldered straight onto the pins. See the screenshot from Smoking Maniac's utube video for the 16-pin USB, which I've modified with the text in yellow). I actually found the plug to have different CC location (the third pin from the opposite end on both sides). Still trying to figure that one out! But, one thing is you might like to scope out the usb-c cable that was originally included with your Grus mod. I might be wrong but have a feeling that someone already mentioned that it worked in a previous comment. So maybe it's already wired up to feed the data+ and data- on the USB-A side to the cc1 and cc2 pins on the USB-C side. Maybe worth a try anyway, let us know if it works.
