2000 Silverado RCSB V6 to Gen III 4.8 Swap

I have no clue what these two connectors which appear to be underneath the fuse box go to. Any ideas? They appear to connect nowhere. Can anyone provide some support?

Show the wire colors. That'll give us a clue what they're connected to. Beyond that, they're just generic connectors.

That said, both look factory. They probably had to do either with options your truck didn't come with, or the 6-cyl vs V8 deal.
