This is what i did. I purchased an alternator clip from the dealer for an 02 alternator. (Part # 15306329). Then i ran a wire from the pcm Red terminal #52 to the alternator.

perfect...that is the exact info I was looking for, but what wire did you hook the redwire from pin #52 to on the 15306329? and did you still use the brown wire that was originally on hte older harness?

It should be the one in the middle. Not sure on what color it is. I'll check later after the rain stop.

mmmmm....rain....

I only wish we'd get SOME soon...

So do you still hook up the same wire that was originally there and then this second wire? I appreciate you checking later.

I have efiliveflashscan, and when I flashed a 2002 operating system into my 99 pcm the battery light started flashing. Just an interesting FYI.
