White is keyed to the ignition and green is ground , those two get the light working on the radio and turn the radio on / off with the key

any chance anyone knows where to hook the other three?

 

Show the rest of it, you aren't getting a four channel speaker system working with three wires that is maybe a power antenna. The audio is probably on the din plug hiding slightly off frame. Wiring diagrams on these are either on the cover or under it usually..

 

I was starting to wonder about that plug , I'm going to go digging around back there but I don't think I have it. Would really like to save the dash , I could never cut it

 

 

Anyone know where or what this wire does? I'm guessing electric choke, which I have. I was doing to desmoging and when I got done noticed this loose

 

You go from a radio to a carb??
the carb wire is electric choke like you said..

 

problem is there are so many plugs with nothing plugged, hopefully I can find a photo I took of the engine
