This splitter cable will allow you to covertly install your OBD II GPS Tracker. Simply snap out your vehicle's OBD port and replace with one from the splitter cable. Then plug your vehicle's OBD into the splitter and plug your GPS tracker into the other cable end. Cables can be concealed behind the lower dash and when someone looks at your OBD port it will be open and functional. HOW TO INSTALL VIDEO
