STOP!!!!!! You will do even more damage to your car if you think you're going to fix this mess. I don't mean to sound nasty, but if you didn't know what you were doing (believe me, you don't know what you are doing), you should have had a professional or someone you have confidence in do this. FIND SOMEONE WHO KNOW'S WHAT THEYA RE DOING! So, here's the first step..... find all the wires you cut, and reconnect them properly (the correct colors, which should not be that hard to do). Here's the kicker.... you saw smoke. Smoke is bad. Very bad. This obvoiusly means you "smoked" something, but it can be near impossible to find what you damaged without tearing the car appart or running a full diagnostic. You'll need a digital volt meter, and a wiring diagram from either Chiltons or simmilar or the factory tech manual. I'm sorry, but you will need some serious technical ability to find what blew up, and no one can tell you what it was by just describing you saw smoke under the hood.

Oh, by the way, NEVER work on electrical with the engine running or battery connected.
