Powerful FeaturesThis breakout box kit can also power the on-board computer, test OBD voltages, and perform other functions. The OBDII Breakout Box can be easily connected directly to the vehicle's on-board data link, providing straightforward access to the vehicle's data bus line. 16 Pins DesignThe input jack layout of OBD2 protocol detector fully simulates the 16-pin layout of the OBDII interface, allowing more tests to be performed quickly and intuitively. When the OBD2 scanner communicates with vehicles, all 16 pins of OBDII breakout box can be easily connected. Data TransmissionBuilt-in input jacks allow connection of any type of 4mm banana plug. Each output port can be connected to a different device, such as an on-board diagnostic tool, a car recorder, a navigation device, and so on. These devices can read the vehicle's data through the output interface and analyze or control the vehicle accordingly. Multiple Protocol Types TestingOBD2 breakout box not
