This device helps you identify if a wire is to negative or to positive, and if neither is shown, then its not getting any contact. It helped out in some cases, but I have to say that when I tried the ECT3000 on an obd2 port, some pins would not interact with the device. I don't really understand why, with that being said it works for a lot of things, but not everything.
