That is probably the rear speaker wiring. Yellow/tan one side, light/dark blue the other.
If that is indeed what it is, a speaker pod should plug right in and work. The plastic pod is the same I think from 97 up but I'd check to be sure. The speakers are cheap, I've had a couple sets quit running aftermarket stereos. But should be ok with a factory unit.
you can buy everything on rock auto,the case, the speakers and grilles,and the extension harness.some people say its pointless because the front over power the rears...but i like it because when im working at the back of my truck i can still hear the music

These come out of the tail light wiring harness
These plugs are in the cargo bay of my 2020 Chevy express. Does anyone know what these 3 plugs are for? I was hoping I could connect a 12v accessory outlet from one of them.
Please use the search function before making a new post. This was just asked a month ago.
One of them should be for a rear window heater so maybe you can use that. The other end probably isn't connected to anything though.
