grand prix gt electrical HELP!!

I just bought a 2001 grand prix gt and I love it but I got some new led tail lights. Now I wasen't paying attention and instead of buying 3057's I bought 3157. They went in ofcourse and after I find my mistake. Well now the gauges and anything that lights up with the turning on of the headlights will not light up. Also I have no turn signals(not even a quick flashing warning signal), and my head lights will turn on but not my rear lights except for when I brake. When I hit the high beams the fog lights will then work. I took out the new bulbs and replaced them with the old of course but it makes no difference. I know its complicated and electriacl problems are the worst but can anyone help me?

Think that you've pretty much shorted it all out. You check the fuses?? I know this has been discussed before over at clubgp.com. try running a search over there
