Initial Set Up

Due to the complexity of modern car electronics systems, all the necessary general information and diagrams must be studied before attempting to install anything. These diagrams act as a guideline, providing an understanding of the wire groups and their respective locations. To clarify, there are three main types of diagrams: a schematic diagram, an actual wiring diagram, and a ground wiring diagram.

Schematic Diagrams

Schematic diagrams provide an overall view of the vehicle's electric systems. Every component represented on the schematic will be noted with an identification number and description of its function. Learning the schematic diagram prior to beginning work on the project is always highly recommended. In that way you'll know where each specific component should be located.

Actual Wiring Diagrams

Once you have identified the components from the schematic diagram, you can refer to the actual wiring diagram to identify the color codes or position of the wires. The actual wiring diagram will have wire colors indicate the type of wire being used. This helps in determining the proper locations of each component during the installation process.

Ground Wiring Diagrams

As the name implies, ground wiring diagrams provide a map of the negative and positive wires. Ground wiring diagrams provide specific connections between components that might not be found in either the schematic or actual wiring diagrams. Having a separate diagram makes it easier for any technician to clearly understand the ground wiring of the vehicle which can make the installation a much simpler process.

Having an understanding of the wiring diagrams of the 1994 model is especially important due to the production year of the car.
