Hello Just noticed that my rear lights and license plate light stay on after turning off ignition switch. Have to disconnect battery to get lights off. Not brake lights !!! Front lights functioning correctly. Maybe faulty dash switch ? I suspect wiring issue ?? Thanks for comments Jim

 

Welcome to the forum.

While it could be the switch, I would tend to suspect a wiring issue because the power to the switch should be cut off when you turn the key off. Just have to get out your trusty DVM and start tracing it out. The factory service manual contains complete wiring diagrams.
