The temperature sensors were ordered from my local independent BMW parts dealer. OEM part number 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.
