I was doing some work on my car, and I ended up inside the glovebox, and next to the ECU i believe. I saw this connection, the black ones, disconnected, and then i connected them.

What is this, and should i re-disconnect it? BTW, I know the PO had a crappy ass electrical guy try to fix a problem and did a lot of crappy things to the cars electrical which turned out to be a bad relay, could this be one of his doings?
