Alarm.com ADC-OBDII-EXT-L Obd-ii Extension Connector

Product Description

The ALARM.COM INCORPORATED ADC-OBDII-EXT-L is an OBD-II extension connector designed to extend the reach of a vehicle telematics or GPS tracking device plugged into a standard OBD-II diagnostic port. It adds cable length between the vehicle port and the connected module, making it easier to route and conceal the telematics unit in tight or awkward under-dash installations. Automotive technicians and fleet installers working with Alarm.com connected vehicle systems will find this accessory useful when the standard plug-in position is obstructed or creates interference with driver controls.

This extension connector is intended for use with Alarm.com vehicle telematics hardware that connects via the OBD-II interface, which is a standard port found on most passenger vehicles and light commercial vehicles manufactured after 1996. It is well suited for fleet management installations, dealer-installed connected-car setups, and security system integrations where cable management or port clearance is a concern.
