I'm going to direct wire in my radar detector today. I would like to tap off a fuse where the 12V is on/off with the key. Car is a 2006 987. Anyone done this before that can save me some experimentation? Let me know the row (A,B,C) and fuse #. That info is in the little book behind the fuse cover. I hesitate to tap off any of the "scary ones like PASM, etc. Thanks.
