![]() ![]() They won’t fit in the original bracket, so they need to be attached to the lower dash with self tapping screws, which is pretty dodgy and probably won’t last forever. One issue is the way they connect the car. I found a replacement OBD2 connector on Amazon for only $12! If you check with a connector supplier, you’ll find pages of possible connectors (the plastic part) and pages of possible terminals (the metal part). ![]() What I mean is that any male OBD2 connector can plug into any female OBD2 connector, but the way the connector is attached to the car and the way the terminals are installed into the connector is different on nearly every car. Unfortunately, OBD2 connectors are all different. If OBDII is a standard, all the connectors are the same, right? The connector was designed to supply power to a scan tool for short periods, not run a current-hogging device all the time. Not enough to blow the fuse, but far more than normal and all the time the car is running. Another problem is devices that draw excessive current from pin 16. One issue is oversize male pins on the device stretching out the female terminals in the OBD2 connector. Why am I picking on the aftermarket? Because the engineering and quality control isn’t as good on a lot of it. The other reason is aftermarket accessories that use the OBD2 connector – insurance baby-sitting dongles people install for a discount on their premium, aftermarket gauges or data recorders, that sort of stuff. ![]()
