Treat electronics as one system rather than isolated boxes. Power, mounting space, data connections, radio-frequency interference, driver controls, and service access are shared constraints.
Map the whole system
List every device, power draw, connector, mounting position, control, antenna, sensor, and software dependency.
Protect vehicle functions
Modern driver-assistance, airbag, camera, battery-management, and infotainment systems require vehicle-specific installation planning.
Leave room to expand
A modular wiring and mounting plan can make future upgrades safer and less expensive.
