Stop unplugging and replugging your OBD2 devices every time you need to switch between them. This full 16-pin OBD2 Y-splitter adapter lets you connect two OBD2 devices to your vehicle's single diagnostic port simultaneously — no data loss, no signal conflict, no hassle.

The male connector plugs directly into your car's OBD2 port, and the two female extension ports give you a dedicated connection for each device at the same time. Perfect for running a GPS tracker alongside a scanner, pairing a dashcam recorder with a live diagnostic tool, or using a performance monitor while your insurance telematics dongle stays connected.

The full 16-pin wiring means every pin is routed through to both outputs — unlike cheap 4-pin or partial splitters that cut off CAN bus and other data lines. Works with all OBD2 and OBDII compliant vehicles made after 1996, including cars, SUVs, trucks, and vans. Plug-and-play with no tools, no installation, and no technical knowledge required.
