electrical dilema

I have not had any lights on my car in twenty years and tonight everything lit up like a xmas tree except the Dash lights and guages. I think it is something stupid that when I got my dash redone I forgot to hook up. I got taillights,headlights, turn signals,interior lights. No dash lights, no horn unless I pull the wire off the horn. Me and jim Beam cant figure it out but I am still smiling at what was accomplised. No gas guage and no idiot lights. Tell me whats wrong......
