Ok, according to 2) your car has lights and starts now? You earlier post said you didn't have lights or anything.
I would say the best way to fix this is to
1. Get you a wiring diagram- priceless..
2. Get a decent soldering iron, flux solder, quality (thick) heat shrink, and a new piece of fusible link (you can buy this at your local NAPA dealer that has the plastic tag on it like the original did).
3. Do a good quality repair (solder, heat shrink- keep it all real neat). Make sure to look at your the spade connector and see if there is damage. Repair as needed ( you can get new connectors at NAPA also).
Here is one of many articles out there about repairs to the bulk head connectors.
