Thanks Mike. Exactly the info I was looking for.
ccjazz - you are supposed to be able to do this with ver 6 Durametric, but I have heard some say that it didn't work for them. The way I understand it, it works on the older cars (99, 00) without first installing the lever or a switch and that will give you ambient temp display only. But, on the newer 986's (01 - 04), you need to install the lever first before it will give you a display. That's if I'm understanding what I have been reading correctly.
Search 'OBC hack' and, after reading all the threads, you'll probably be just as thoroughly confused as I am.
