hot box

[CJJ67]

I've got another question. What are you all doing with all the wires for things like the alternator, electric fans, etc.? Everything can't possibly get hooked to the battery on the hot/negative wire(s). Is there a junction box or something that can be used to hook all the extra hot/negative leads to so that one wire is ran to the positive/negative terminal(s)? Anything to keep it organized and clean under the hood.I hope I asked that question right. Thanks for any help.
