The USB to 3-pin temperature probe header cord that came with my unit is sure a tight fit on the header pins. So tight, that when I went to pull it out, the wires came out of the 3-pin connector. I'd like to reseat them, but want to be sure the right wire goes in the right hole -- what's the correct wire order, from pin 1 to pin 3?

Here you go. The two black bars are the raised areas on the plug. Don't trust wire colors. Check the signal with a voltmeter if you can. This is a temp probe, but it's the same. You need to connect to the two outer pins.
