Smells Like Fire!

If your blinkers didn't work I'd start tracing those wires and any power wires that you added for any aftermarket electronics. They may not be what's shorting but might be near enough to what is that their insulation melted. Look for melted insulation or smoke. Also feel the wires because if it's shorting it will get warm. Inspect the wires really closely where they pass through any firewalls or bulkheads. Also once you find the problem, look for collateral damage. Any wires in close proximity to the shorted wires may have also melted. Keep in mind that an electrical short can quickly burn your car to the ground so be ready to disconnect your battery while you're troubleshooting.
Good luck! and happy hunting... I hate electrical shorts!
