A system and method for tamper detection in wired tracking devices uses an identification mechanism embedded in a connecting cable, displaced from the tracking device. An asset tracking device attached to a trailer periodically tests for presence of the identification mechanism at the opposite end of a connecting cable. Identification mechanisms can embed in cable wiring or use discrete components. A missing identification mechanism indicates cable tampering. By implementing the identification mechanism to the far end of the cable, intentional cable cuts can be distinguished from routine power loss. Rapid notification of tampering events allows timely tracking device recovery and repair. Cost-effective deployment uses existing tracking device hardware and firmware functionality, only modifying cable assembly. Broad applicability ranges from vehicles and trailers to remote containers and assets. Theft prevention and detection capabilities are enhanced without added hardware expenses.
