What car, year, engine?

If the black/red wire is thick, it's most likely the el. fan wire. The red and orange sound like power supply wires. The little box on the end of the orange and black wires, could it be a single-fuse holder? If so, it supplies power to the fuel pump, electric fans and the ECM.

The black wires are for the electric fan then.
