s13 fusebox confusion

I just got this 240sx a while ago with a bad lower harness. I dont know too much about Nissans. Just bought it a new wiring specialties lower harness and found this fuse box wiring mess. It seems to have two wires spliced together into a ground and I don't trust it. It also has a severly frayed ground that I'm lookng to replace. I have went to countless wrecking yards to look for an s13 and had no luck. I'm very anxious to start the car because this wiring is very sketchy and looks like it will catch fire by just looking at it. By the way, the car is a 1990 with a KADE swap and I think it might have been an auto in the past. Any help is apprecated thank you.

i was thinking that since the red thing on thee positive terminal a.k.a power feed connector, it needs to have some thing plugged into it, this might be the reason why these go to that terminal. If anyboy has a pic of thewhite wires and where they might lead would really help out

I was doing some looking around and the two wires crimped into a ring was done to avoid having the the red thing in the positive terminal, so I just went ahead and took the red part out and put the ring through the terminal. As for the alternator wires, the black one is a gound and it melted, Im thinking about getting the wiring specialties fuse to alternator ground to avoid this, or how should I go about that?

As of right now i found an s13 coupe a 1992 to be exact. I went ahead and took a chunk of the harness and that one only seems to have the single white wire leading out of the alternater plug instead od of a white wire with a ground.....

You need the ground. Theres a lot of static electricity building up because of the coil and scrubbers. Theres a potential to have power feedback.

Remember, you're creating power with that alternator, you need to ground it just like any other piece of electronics. It'll help stabilize the current coming out of it as well.
