No electronics working besides headlights

[Atill93]

My headlights and the interior ceiling light are the only thing working on my car. I put the key in the ignition and turn it and nothing happens. The car was turning over and running fine about a week ago.

I've already gone over the entire wiring harness and cleaned up a ton of connections and i've tried three different batteries.

any idea what it could be?? please help!!

Gonna have to get a multimeter and start checking connections for power, everything that isn't working shares the fuse box in the engine bay.
