Tips: If you already use the parallel port for car detection  you can also use this kit but because Pc Lap Counter manage only one parallel port  you have to make a special cable with one male and two female who separate input pin (1,10,11,12,13,14,15,16,17 and ground pin 18 to 25) and output pin (9,8,7,6,5,4,3,2) like here:
