What’s this plug under the driver dash?

What is this plug? It’s under the driver dash next to the gas pedal and ac foot vent.
I’m having radio issues. Making sure this isn’t the reason.

Sorry I have a 2000 mustang gt

That doesn't look like any of the plugs I've messed with when dealing with the radio. But my front amp is still in place. What issues are you having?

I have no constant power. The fuse checks out and there is power coming out of the fuse. But no power to the radio constant

What about the wiring between the fuse and the head unit? Is the head unit forgetting the settings?

Just looking at wiring diagram there are a couple fuses ..

What fuses exactly are you looking at?

See premium or super sound system.

That connector hanging.

Wire colors will help to determine where it goes .

Can you share the wiring diagrams you’re using? Or have a link to the correct diagram?

When I jumper the constant the head unit turns on. Besides the fuse under the dash is there another fuse or connector for the radio?

That's odd. It was always my understanding the constant was just so the head unit wouldn't lose the settings and the key on source is what turned it on. I connected both power wires to the constant in an old work out so I could listen to the radio without the key.

Are you sure the harness is correct? As far as I know there is no other fuse besides what's in the fuse block.
