Agreed with the post above. Non sensored so wires can be anywhere. I'd just make sure that B is to B and only switch the 2 outside wires if needed.
My guess
Crazy on how all my Hobbywing combos are labeled. These are sensorless too.
That's Traxxas for you. They don't label letters. They color code it. Because they want you to use that motor with the VXL 6s ESC and nothing else.
Looks like Black wire would be B. And White and blue will either be A or C. My guess is white will be C and Blue will be A
