The mounting location should be carefully selected. In the interest of passive driver and passenger
safety, the ZBP-1PRO must be securely mounted, and precautions must be taken to allow sufficient

may be damaged by the drilling of the holes for the processors mounting screws. The processor
must NOT be mounted directly to the chassis ground of the vehicle, this may cause ground loops
