Engine fuse box

Is the old fuse box badly corroded or physically damaged? That's about the only reason for changing one. Technically any fuse box would work, but one that's the same shape with same mounting points and has labels in correct spot would work best (ie one from the same model/year as your car). If you can't find an OEM one for a 97 Neon, no big deal, just use a generic one or kit one you can get anywhere. Parts stores have them. It goes without saying, you have to replace it exactly right, so have a wiring diagram on hand, take before pictures so you know what went where, and follow a tutorial or guide, plenty of those online.
