So here's my update.

Problem: Tail lights and parking lights come on when battery connected.

Headlamp switch and brake switch disconnected. Tail lights and parking lights still come on when connected to battery.

Connector on steering wheel disconnected. Tail lights and parking lights are off when connected to battery.

Using my ohm meter I checked resistance to each parking light housing and frame. Good ground indicated. I also checked the tail light grounds and those appear to be fine.

Since the marker lights do not come on and the turn signal lights and headlamp bright light is lit on the instrument cluster I am thinking it might be a shorted circuit board. Before I go that route I wanted to see what you guys think. Thanks.

One power supply that has not been mentioned here is the emergency/hazzard flasher.
It too works like brake lights. Has power all the time. That circuit lights up all four corners and turn indicators on dash. With a bad emergency flasher and an accidental push of the emergency flasher button, you could very well have what's going on here.

So work the E flasher button in and out. Put turnsignal harness back together. And see if you even have a problem. Other than possibly a bad or wrong E flasher keeping this from being an obvious problem
