Does not work on a LT1 or L99 PCM. Search "paperclip code" on this forum.

Everything is here and EEHACK is on my computer and I'm amazed really. What do the Rx and Tx wire go into which port? I know ground but not those two. I'm using this pic to guide me. Don't wanna ruin anything but being able to change stuff relatively on the fly is a pretty cool luxury.
