Help with no headlights. 1974 scamp. Blinkers come on instead...

This is what im looking at.

So with my cluster out entierly, and the 2 ammeter wires tied together, my blinker issue persists. U would say that eliminates the headlight switch...

With the cluster out, and the dimmer switch unplugged, the dimmer switch plug has grounds on the outer.

I see in the diagram that the driver side bulkhead has several headlight wires running through it.

I will probe them and see what i can find. Am i dumb to assume "red" is hot on that plug...so sending power to that wire should turn on the lights?

And the blue thing in my pics above...thats the seatbelt interlock right? Can that box just be removed?(unplugged)
