The black rubber in the middle is the test button. A black plug with 2 wires goes in to the orange part of the cap. You will have to look around maybe the wires and plug are wrapped up around something or maybe they were even cut off. I also recomend you remove the cap and the little plastic resovoir that the float lives in and wipe it out. Look at the brake fluid. If the fluid is dark and there is a lot of dirt in there I would suck out what is in there, wipe out the resovoir as best you can, refill with Castrol GTLMA DOT 4 and flush out the brake system. Ditto for the clutch if you have the 5-speed. You should change the brake fluid every 2 years to avoid any corrosion problems as required in the owner's manual. This also keeps the bleeders from freezing up, flushes out any dirt and air, and keeps the boiling point of the brake fluid high. If the P.O. did this (or his mechanic) you should be suspicous of ALL the work done on the car. Whoever did this was reckless and had no regard for the safety of the driver of that car. By disconnecting that plug you would have no warning if there was a serious malfunction in the brake system. Make sure the emergency brake is fully functional and check the brake pads and brake hoses.
