I'm in California, USA and I am familiar with those distributors, thank you. My problem, which I failed to explain clearly, is that I don't know how to precisely identify the connectors the Chinese used. I was hoping that someone on CNCZone had already identified compatible connectors that are available from distributors such as the ones you listed. Otherwise I'm left with voiding the "3 year" warranty on the stepper motors by cutting off the weird connectors from them and replacing them with Molex connectors, and maybe replacing the spindle connector with an AN connector from Amphenol. I don't know if the Chinese warranty is worth anything but I hate to void it without at least checking here first.
