No Tail Lights, Dash Lights, Running Lights

So I had when I turned on my headlights, I would have headlights, but no other lights(dash, tail, running). I tested checked fuses, all good. So I figured it was the head light switch, put a new one in, same issue. Checked the switch with a test light, its getting power but only sending power to the middle three prongs, not the top or bottom prongs. I hooked up wires directly into the female connector, the power coming from the middle connector, and feeding two wires, one going into the top and 4th female connector space. With the wires, everything worked, I figured I just bought a bad switch. So I exchanged the switch for another new one, get home, and same thing, just headlights. What is causing this?

Search for the link to the factory service manual. Look at the wiring diagrams. There is a reason that only the inner connectors have power.

Loose the scotch locks.

I don't see a reason based off of this wiring diagram that would explain the issue

Is it possible the female plug is wired wrong?

Your tail light fuse is out. Look at this thread.

If it were the fuse, wouldn't the lights not work at all? I'm giving the female headlight switch connector power and the lights work, they only don't work with the switch.

read the thread. When the tail lights are out the instrument lights go out.

You were right, the Turn Signal, Park and Tail Lamps fuse looked ok, but to be sure I swapped it, and it worked. The switch gets two power sources and the fuse is prior to the switch, not after the switch, which explains why they worked with power applied at the switch. Thanks!
