I've got it, but it doesn't cover the early 944 climate system in depth like it does for the later models. I've been looking for a late 924 manual but haven't come across anything. So is the Climate Book part of the 928 Work Shop manual?

I was able to source the part I needed, so all is well. I'll head back to "my side" of the forums now.

The Newark link was not working for me so I researched several thermistors that approximate the factory sensor specs. The one I purchased from digikey and tested is listed as an NTC 470 ohm, 5% thermistor. That means Negative Temperature Coefficient (i.e., lower resistance at higher temps), 470 ohm at 25C, 5% error. There are others, but I liked the one with this small encapsulated bead and long leads. I soldered the thermistor to leads to the harness connector, potted it with polyurethane, encapsulated it in shrink tubing and placed in the alternator duct. Sensor cost was under $2.
