Maintain OBD Port Access
The OBD-II Pass-thru Cable allows continued access to the vehicle’s OBD-II port when another device is already installed. It is commonly used when a suspension bypass module, data logger, insurance tracker, or range monitor occupies the factory port.
The cable installs inline and provides a full 16-pin pass-through connection without blocking communication or limiting data access. All standard OBD-II functions remain available, allowing scan tools and diagnostic devices to be connected without removing existing hardware.
This is a simple, plug-and-play solution for vehicles that require uninterrupted OBD-II access.
