I just got an AM radio and I only see 2 wires coming out of the Radio. I am assuming the radio grounds through the case, but I am trying to figure out how to connect a speaker and how to power it up. Anyone has a wiring diagram for this?
Thanks!

Welcome to the FFO!

Should be 4 wires.
Two for a speaker in front. Mounted on the instrument panel
One for power. Should be 12v+ when ignition switch is on run or accessory
One for lighting or illumination. Should be 12v+ when the headlight switch is on parking lights or head lights. Many times this is a red/blue wire.

Yes the case grounds. Typically via a mounting stud on the back of the case.

Thanks for the feedback! Do you by chance know which wires come from the left side of the radio? (volume knob side)

No you would have to post a picture. There are several variations

So for the radio I have (model 22BD), the speaker connections are on the right hand side (same side as antenna connection), located right above the antenna trimmer.

On the left hand side, blue wire goes to light switch, and black wire goes to fuse/battery.

Putting it here in case someone needs it in the future.
