Visible wiring that is insecure, inadequately supported or likely to cause a short will also result in a failure as will wires bared by damaged insulation.
The car will fail if a speedometer is not fitted, is incomplete, inoperative, has a dial glass broken/missing or cannot be illuminated.
It must be possible to secure the driver's seat fore and aft adjustment mechanism in two or three different positions
