Temperature sensors order from BMW part # 62110788115. They are just the simple one wire-hookup type, the housing is the ground. They were very easy to calibrate actually. A lot easier than I thought. Just get yourself a known working thermometer and freeze and boil some water measuring the Ohm's at 3 three known intervals. Here are my results

F	Ohms
44	1.300
80	0.568
185	0.73

I then plugged them into my MegaSquirt and they all checked out. That simple.
