It is the one circled in red, and I believe it goes from the controller to the display cable harness, but that might not be right because I see 5 or 8 pin cables when I search for display cables (https://www.ebay.com/itm/For-Bafang...ss-Cable-BBS01-BBS02-BBSHD-kits-/392616731206). It looks to be a 10-pin connector. Both male and female connectors have 10 pins on my bike (Rad Mini 2019) and controller (linked below). That controller is wired for Rad Runners, so that particular cable is short for the Rad Mini. I wanted to see if there are cables ready before I just spliced wires in to extend it.
