Yes, the yellow wire is the switched hot lead - it is typically connected in one way or another to the ignition switch. There is also a smaller gauge red wire that is connected directly to the battery (through a fuse of course). Both of these wires have to have power for the radio to work. Also the black wire has to be connected to a good ground. If all three of these wires are confirmed to be in good order (power where there should be power, ground where there should be ground and no shorts) the radio should at least power up when they are all hooked up and the ignition is on.

Need help finding parts for a marine radio I bought at a rummage sale, It is a Sea Worthy,Sea9504 AM/FM cd player. Just have the radio,need wiring harness, and a antenna .Don't know what else i need? Don't want to buy another one. Have speakers to. Besides E-Bay taking a chance that the parts might work. Went to sites on the internet.Do you know where i can get these parts cheap,If you could help me.looking to purchurse by check not by credit card.

IT may be to late but you can buy a JVC radio model KD-SX50M tat will be plug and play. I just purchased one for 69.00. I had a simialr situation and that was all it was.
