Mystery Electrical Box. Take a look. What is it?

[CuzEddieClassC]

I am rebuilding/refurbishing a 2002 Class C Ford E350. Some electrical issues.
In chasing wires I pulled up the bed platform and found this box. No manufacturer. Only marked with "Made In Korea" (When's the last time you saw that?). The wires come out from the bathroom/under the shower pan. Guessing its either a relay or some sort of auto reset circuit breaker.

Can you chase the wires back to somewhere?

 

[CuzEddieClassC]

Will do. In the morning.
HOWEVER ... just had the thought it might be an old school trailer brake controller. Why it would be completely out of sight is a little bizarre.

If it were a trailer brake controller, it would have a manual operation lever on it. The only type I've ever seen that didn't were surge brakes built into the tongue.

I don't have a clue but find it interesting that it was made in Korea. You don't see that very often!

Can you open the box? Might a clue inside?

Yeah, open it up! Did tracing the wires offer any clues? Interesting location, I’m feeling like it’s some kind of voltage regulator

Ohhhh….is the bed in the front of the RV? Looking closer at you photos it appears there is a red and black wire then 2 red n white wires together, then one far to left all by itself.This very well could be a brake controller with left most wire being the brake apply “ brake light “ the next 2 being 12 volts + and - and the last two on the right would go to the electric solenoids in the wheel drums.
