headlights, running lights, and turn signals all messed up

This is my first post and I had trouble actually finding any kind of solid information on a wiring diagram for the problems in the title. My running lights appear to be wired into my headlights so they are always on and my turn signals have been wired into my running lights. When I switch my headlights to the "on" position they just get little brighter. If someone can link me to a page that covers this or provide information that could help me revert it back to normal, that'd be appreciated!

I have a 2002 TRD 4 door model.
