Add-On Electrical Equipment

Print

The electrical system in your vehicle is designed to perform under reasonable operating conditions without interference between components. Before any additional electrical equipment is installed, it is recommended that you consult your dealer or a reputable repair facility that is familiar with the vehicle and its systems.



Install the antenna as far as possible from the control module. For instance, if the module is located behind the center console area, then the antenna should be mounted at the rear of the vehicle.
 
Keep the antenna wiring a minimum of eight inches away from any wiring running to control modules and from the module itself. NEVER wind the antenna wire around any other wiring.
 
Mount the equipment as far from the control module as possible. Be very careful during installation not to drill through any wires or short a wire harness with a mounting screw.
 
Insure that the electrical feed wire(s) to the equipment are properly and tightly connected. Loose connectors can cause interference.
 
Make certain that the equipment is properly grounded to the vehicle. Poor grounding can damage expensive equipment.
