Only thing I still have connected is the door lights, everything else isn’t connected and doesnt draw. My radio is also fried and pulls 12.5 volts at the deck wires.

The voltage measurement is the wrong measurement for a parasitic battery draw. You can measure ~12V at any wire that is hot at all times, but that doesn't mean you are drawing current.

You need to hook up your volt meter in the amp setup where you disconnect a battery cable and hookup the meter between the battery post and a battery cable. I suggest you do this on the negative terminal. Your setup will have the wiring going through your volt meter. You want to keep contact through the volt meter when removing the negative terminal through your volt meter, so slightly lift up the negative terminal and have an alligator clip to connect to the battery post under terminal. Also have an alligator clip on the negative battery cable. Hope this makes sense. pinehollow diagnostics on youtube has some good videos on parasitic draws that should help.

I got it. My radio was the draw. Running the tests you sent just confirmed it was my radio deck. Cheered mates, thanks for the help
