Fuse box swap?

[4Runner4Leon]

I want to add more fuses since I'm starting to upgrade my '97's electricals (power outlets, seat heaters, heated mirrors, maybe fogs).

I guess most most folks use an add-on fuse/relay box (Bussman) for such upgrades, and I might to. But being difficult, I am wondering how hard/easy it would be to swap in a factory fuse box from a newer model, e.g. a '00, which would already have all those circuits. I am thinking that it would be a lot of very difficult wiring trying to make it work, and the Bussman box would be much cleaner - but I just have to ask.

Would I be a glutton for punishment trying to do this?

Yes. Besides the external wiring which would be a major PIA, some of the internal wiring of fuses and relays likely changed between the two years and that would be a killer.

Thanks for the quick response! I suspected as much, so I'll get the idea out of my head.

What are the basic considerations on adding a box under the hood vs inside the truck (I've seen both setups)?

Is it a matter of where I expect most of my add-ons to be (e.g. lighting/horns = under hood, stereo/heated seats and mirrors = inside)? Or are there other considerations?
