This is an OEM OBD to HDMI box used for tuners such as Bully Dog and H&S.
We have gotten requests to add the other cables that connect to this box, the HDMI cable that runs from this box up to the tuner's HDMI port and the power wire used to give the tuner a switched ignition source to enable the tuner to turn off and on with the vehicle.
The OBD box is pictured, the HDMI cable is #6 and the power cable is #2 in the 4th product photo.
