Installing one of these picked up at a garage sale for $5 condition unknown. The power connector coming out of the radio has four wires: Black (presuming negative), Red (presuming positive) and a small white wire, and a small black wire with white tracer. I don't know what if anything to do with the two small wires as the manual is unhelpful. Can anyone advise? Also, how moisture resistant are these radios?
Thanks.
Thanks.
