Electrics are like the black arts for me, so I need your help in identifying what's going on here.

What is that relay box for?
Can you say from the pic if it's still in use?
Why are those wires joined together?
Did they originally run to that box?

Thanks in advance.

That is an external voltage regulator. The wires are grouped together because someone has converted the truck to an internal regulated alternator. It's good.
