What are the connections on this radio

Put some penetrating oil on them and let it soak overnight. This will break up the rust and other build up. Make sure that it is penetrating oil, you can get it at any automotive store.

I realize that I need to advance the timing to increase fuel intake to match the extra air, now that my cold air intake system is installed. How might I address this without taking my miata to a mechanic?
