Forgive a mere mortal wot hasn't had a V8 now for many a long year.........
Apparently Rave does reference it somewhere:... saw a reference to section 19 somewhere?
In the Rave manual, it shows a picture of two engine coolant temperature sensors, but in the description, it just talks about one (my guess it is talking about the one with the single bullet connector. It says it should measure 28k ohms at -30 degrees C, 300 ohms at 85 degrees C, and 90 ohms at 130 degrees C.What is the other sensor for (the one with a two prong connector)?
Found the above comment Here
Also found This and This too, on the basis that the sindle pin sensor is AMR1425, 'green' which I think is correct.
