I've read that I'll need to use an adaptor plug (4L60E has a different plug than 4L80), use a spacer, and oval the holes on the flexplate. My PCM has pins for 4L80E, but I can't find much info on how to wire the 2nd VSS plug. Any help would be really appreciated!

Not to sidetrack this thread. Skymangs please create a thread in the forum and I can answer all your questions with the 4l60e to 4l80e swap.
Put it in the LSX engine forum.
