Generation IV External Engine - Please help me identify these harnesses?

These were included with my '05 vette ls2 pullout, but i'm not sure if they're from the engine or not,given the source (read up on Craig Payne for more info!). What are these from and are they worth anything?

Sorry for the blurry pics.

That number on the tag would be: 15808059

I did a search and couldnt find anything! Please help me.

Looks like i have an '05 vette harness/pcm. Is it worth anything to anybody?
