I HAVE NOTHING BUT HEADLIGHTS "update '

Let me start from the beginning. I started with headlights & all park lights except for the left front. I put a new bulb in & then checked the turn signals. I have no turn signals. I found that the turn signal cam was broke & i had blown the fuse for the interior lights. So i replaced the cam & fuse. Now i have nothing at all but the head lights. No interior lights, park lights & turn signals. All the fuses look good & the fuse box isnt all rusted up. Wiring issues are a big problem for me. Most times i dont even know where to start. Could it be as simple as the head light switch is bad ? OK i got everything working but turn signals & dash lights The dash lights im thinking its because i changed to LEDs Now when i turn the flashers on it blows the fuse that says "tail lamp & stop dome. Thats the only fuse that blows. I also down loaded a 67 barracuda wiring diagram & i cant see anything that would make that fuse blow
