it should be your starter solenoid. Your positive terminal on your battery will have one wire running from the battery to a terminal on the solenoid. (there might also be a few more smaller wires leading to that terminal from under the engine) Another wire should be leading from the opposite terminal on the solenoid directly to your starter. There will also be one or two smaller terminals on the front (one labeled "s" and "i". the one labeled S will have a much smaller wire leading to your ignition on the column.
