New dash lights stole my energy.

Hey guys, I'm really new to wiring but i decided to pull my instrument cluster to replace my lights and put in a new voltage regulator to try and problem solve my gas and temp gauge from not working. I got all the new lights in and cleaned everything up. I put everything back in and got it all buttoned up but now my car wont start. My ignition turns and i get power to lights inside but not even a clicking on the starter. The worst part is that not all the lights are working after all this. Any ideas of where to go next i have no ideas of what to do with any of this. Its a standard dash on a 69 Dart. Thanks for all your help!
