My datalogger runs off the laptop. I found a secret place to get the obd-ii connectors and going to be making some probably and selling them cheaper than the http://www.obd-2.com/ website. They want $122 dollars for them. Noone else can seem to get the connectors which is why many people dont sell them but I found out the secret to them. And no I wont give it up. The cable I have came from the OBD-2 website.
