Found strange box spliced in under dash

I was looking under the dash earlier and came across this weird box spliced into the wiring harness. it has 4 prongs on it and 3 wires going into it, one of the wires is connected to 2 of the prongs. Any idea what this is and why it's there? I'll try to take some better pics tomorrow when lighting is better.

The 3 wires that were cut look like they went into here before...

There is a small diagram on the front of it, I couldn't get a clear pic of it, but it looks like this:

Can I just take this off and solder the 3 wires back together? I know this is kind of a stupid question, but I want to be sure before I go messing with wiring and what not.
There's alot of ghetto wiring done on this car. I also found a plug to hook up to the lights on a trailer spliced into the taillight harness.

I also found a piece of gum, still in wrapper, behind the trim piece
