No power at all, help with wiring please

I picked up a 1970 dart with a not original 318 in it. I think it was a slant 6 from factory. I don't know anything about wiring . But I have no power to anything at all when I turn the key. I have good battery, new starter relay, 12v regulator, ignition switch in steering column and new key and tumbler. Here's how it's hooked up right now...I put it back after I replaced those parts to how it was when I got the car.image.png ..let me know if this is wrong
Yellow circled wire goes to battery. Orange goes directly from positive battery post to starter. Green goes to starter solenoid and the blue goes to I'm not sure lol but it does go behind the firewall I know.
