Need some help identifying wiring and connectors

[Knuckle Dragger]

I hope this is the right place. I need some help identifying some wiring. I was pretty heavy handed and rushed when I did the 5.3 swap. I'm replacing the dash and trying to clean up the embarrassing wiring. I have some factory wiring I don't know what it is. I have a guess but hoped you guys could tell me for sure. IT will save me the 20 mile trip into work to pull up the diagrams.

It's a 1994 C1500 Silverado originally with the 4.3.

I think this is radio wiring.

You’re right about the radio wires, I believe the red plug is for the cruise that plugs into the VSSB. The rest also plug into the VSSB.
