Hey guys, just wanted to clear up something: The WatchDog CAN run on just OBDII power alone. The power wire is optional. However, if you don't run the power wire, there is no option to have "key on power" for it. To be clear, you can run the WatchDog without running a power wire, so it is plug and play. But the OBDII port is not wired to key on power, so you have to manually switch the WatchDog on/off at the OBDII plug (with a provided switch) if you choose not to tap a key on fuse. (and if you don't switch it off when you get out of the vehicle, it will continue to draw power.)
