Can you share the wiring diagrams you’re using? Or have a link to the correct diagram?Just looking at wiring diagram there are a couple fuses ..
What fuses exactly are you looking at?

That connector hanging.
Wire colors will help to determine where it goes .
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?What about the wiring between the fuse and the head unit? Is the head unit forgetting the settings?
