So I just bought a 2000 GS-300 this weekend and today I was putting in a battery, when putting it in I switched the negative and positive terminals on the battery and hooked the cables up wrong, It sparked and the horn went off. I blew the ALT relay 120A and some others. I bought a new ALT relay at the dealership for $20 (ouch!). My problem is that I can not get the 2 prongs out of the terminal where it goes from the old one. The plastic box with the little plastic window came out leaving 2 prongs there that just will not come out. I tried everything up to vise grips and called it quits. Does anyone know how to get those things out, The car will not start now and I assume replacing this will do the trick. Thanks.
Here is the two prongs stuck in the fuse box
Here is the new one I bought
