Vehicle Zoning Strategy
All grounds, in-line connectors, and splices have identifying numbers that correspond to where they are located in the vehicle. The following table explains the numbering system.
| Callout Numbers | Zone Description |

| 200-299 | Within the instrument panel area |
| 300-399 | Passenger compartment (From instrument panel to the rear of the passenger area) |
| 400-499 | Luggage compartment (From the rear of the passenger area to the rear of the vehicle) |
| 500-599 | Within the driver door |
| 600-699 | Within the front passenger door |
| 700-799 | Within the left rear door |
| 800-899 | Within the right rear door |
