Used for holding vehicle memory while the battery is out, this jumper feeds power through the OBD2 port from a cigarette lighter source. It connects on the positive and ground pins only, so it will not interfere with stored fault codes. A high-visibility coiled cord resists tangling and stores in a tool box.
