Sorry, the 18 circuit Painless harness. I got rid all the Jap wire. Most radios have a wire for operating the antenna, usually its yellow. You have a power wire to do the work but this other wire I think sends the signal.?? Mine isn't ready for a battery yet, so I'm hoping it works. A Haynes manual has a good diagram you need a magnifier to read it. You can trace it back to see how the original wiring is suppose to work. Hope you not more confused now.
