I just replaced my heater core following the guide on the forum. All went well, except my radio, blower, and 12v outlets aren’t working now.

I checked the fuses, relay, and various connections. It seems like there’s a common ground that isn’t connected somewhere.

I also found this random wire connected to 12v outlet but not going anywhere. Greatly appreciate any help.

Yes, it sounds like you're missing a ground.
Probably on the firewall behind the HVAC.

That random (speaker wire) is a hack job, remove it.

Does your dash and/or switches light up?

Dash and lights oh the hvac light up. No lights for the OD and no power to either of these 12v sources.

There’s a ground behind the HVAC on the firewall? I guess I plan on ripping it all again tomorrow, but I have no idea what I’m looking for or where to find it.

I was kind of kidding. I know what a pain pulling that is.
I'm actually not sure where those grounds are at.
Have you checked for 12v at the power port using another ground?
Keep in mind, only one is constant and the other is keyed.
