What went wrong, fire Options

[914itis]

I decided to install my hangman fuse panel. after installing i started the car, turn on
the head lights - works
flashers- works
turn signals- works
decided to turn on the wipers works, then the engine cuts off followed by a spark on the fuse area. within seconds the wires was on fire. I safely put out the fire.

I then removed the fuse box, to notice that the big red wire was burning, that wire was attached to a brown piece that looks like a breaker. it cracks ast it burns out.

My question is what is that brown peice is used for that has the brown wires attached on one side and the big red one on the other end.. I know that the brown wires are ground.

now that peice is gone what do I do..?
A good portion of the red wire is melted. and I will be inspecting the rest of the wires for burnt.


help!

I see some serious melting on a couple brown wires there as well. Go through everything you did, too long of a screw somewhere, bending a wire that broke insulation, etc. . Did the bake light piece break while moving stuff around, then short out.. Lots of possibilities there.

I am almost sure that a Long screw caused it.
the rest of the harness don't look too bad.I went and got a 4 gauge wire to replace the urned one and I wil I have two othe short wire thr are damadge but they are easy to repair. For safety I got myself a 60 amp fuse that I will put right by the battery. I have all the parts and planing to work on it tomorrow.

You mentioned the brake switch box. Is there an other one other thn the one by the pedal?l
