how are the headlights ,radio, dash lights, and neutral safety switch all tied together?

how are the headlights, radio, dash lights, and neutral safety switch all tied together? i was driving and all went out i pulled over and put it in park and coundnt get it out of park

I have a 93 Tracker and have basically the same issue. I have replaced the brake switch and the light switch assemably. Still no lights, radio, brake or running lights and shifter still locked in park.

Anyone have any input help. Basics have been checked already.....

Has anyone responded to this post? My '94 Geo Tracker has very similar problem with the interior lights (dashboard, radio, dome lite, etc..), just no problem with the neutral safety switch.
