Key ignition light

Hi guys. Hopefully someone can help me.. My 72 Duster has the interior light group. Map, ashtray, glovebox and ignition light in the column. My problem is with the column light that illuminates the key switch. It never goes out when the quarter or headlights are off. I’ve replaced the relay with a new one and it still does it. For now I’ve disconnected the wire to the light. So it won’t drain my battery. I’ve had this problem since 1995 the year I finished restoring the car and always had to disconnect the battery with I got home. I’m sure I plugged something wrong now but no idea what. Any thoughts on this guys?
