Headlight problem

[Rxguy667]

I can't seem to get my headlights working. New bulbs, signals work, all though the back ones are reversed. Brake light, but no running light. The taillight running light is on, but it's so dim it's barely burning. Also I don't have a horn. The hi beam light doesn't light up on the dash either. Possible grounding issue? I've had this thing completely apart and didn't notice anything disconnected.

What do you think?

Thanks
Daniel
