Hey
@altivec ... I'd love to help you out, but have failed for the most part to build reliable temp sensors. The size of the connector, and the gauge of the wire is just so small, every attempt I made resulted in the wire breaking (I got 1 out of 10 I tried working for a while, but it did break as well when I removed it)
It's a 10k thermistor that you need for it, and it's a JST connector. You can get the crimp pins and connector from DigiKey, but I'm yet to find a suitable thermistor I can get crimped on with any success rate (I don't think my <$100 crimp tool from Japan is good enough for this, they do sell one from DigiKey for >$1,000 that might do the job ... but obviously one would have to have the need to crimp a lot of connectors to justify that type of cost!)
Edit: I did have a spare a while back from a broken unit, but already sent it out to another member quite a while ago. Hopefully someone will pipe up here with a broken Crafty ... the circuit board does fail on them sometimes ... I'll also try to go through my messages and find 1 or 2 people with defective circuit boards to see if they might want to sell you their sensor.
