Thanks to bluegtp91 for posting a picture of the '97 pcm.
It is my understanding that whatever that additional sensor happens to be, it, as you noted is for a '97 model. The two pcm's I have do not have that sensor as they are both pulled from '98 models according to the sellers, thus my query.
From what I can tell, while there is plenty of compatibility and interchangeability of plenty of items on the 97-03 models, however, in the case of the '97 pcm, this is one area that lacks compatibility.
My goal was to be sure about it, and the postings confirm my suspicion.
Appreciate the help.
