5 Wiring and Terminations
5.1 Example Vehicle Wiring Diagram
The following drawing shows an Adept Validator installed in isolation, with only general reference to external
devices.
The example diagram is mainly for the Adept Validator end only, any interconnection and extension between the
Adept Validator and the terminal end needs to be discussed and confirmed between the customer and VIX.
