Check those two top spades to see if they are switched or constant power. The factory radio will have a switch power connection for you. The modern radio will need a constant power source too for memory.


I would look into a glove box mounting kit if you have not already. cutting up the dash just kills resale value.


I would look for a radio delete plate for the trim or just leave the stock radio in place. Now one will try and steel your radio if they see the old crappy AM radio.
