Notice: GM cannot be responsible for any changes made to the vehicle. Have all electrical and body modifications performed by experienced technicians.

   • Be sure that any modified or added wiring will work properly with your vehicle's wiring system.
   • See that all wiring is properly protected by fuses, and not causing an overload to connectors and components.
   •  Do not route wiring in areas of the vehicle where temperatures can be high or where wiring may be cut, pinched or rubbed.
   • See that all added wiring is of the same or smaller gauge than the wire it is being attached to for proper fuse protection.
   • Be sure that all holes drilled in the body are properly sealed and corrosion protected. See that the vehicle's wiring harnesses, piping and other components have not been displaced or damaged during customer installations of equipment and wiring.
