Explain to me how factory AM radio is wired... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I went and pulled my power brakes and brackets, I found a factory AM radio (not worth much to me I have hacked dash, but maybe to somebody esle). How in the world is this thing wired

I got the pigtail with it, the factory speaker and brackets were still there, but they were such a pain to get to I left them. On the back it says [12V (red), SPK (green), GD (blk)]. 12V of course is pwr... SPK would hook to the pos terminal of the speaker, correct? So is the circuit completed by grounding the speaker to the frame? Or is GD the speaker ground, and the radio grounds throught the frame of the radio? I was expecting 4 wires, not 3.

I want to check and make sure it works before I try to sell... Thanks for the help!
