i just picked up an oem radio from a 83 honda accord, but i noticed it only has 3 wires 1 grey 1 red and 1 yellow and red. im wanting to put this in my 83 civic but how would that wire up.

*Usually* Yellow would be constant (12v), red ignition, and grey speaker.

well i dont even see a solid gray or solid red on the diagram, and its just an am fm radio so why would it need a constant power ?.

ok i got it figured out, the yellow and red is the hot wire as said, the solid red and solid gray is the positive and negative for all speakers.
