The OBDII power supply only connect to the battery positive and negative contacts inside the plastic connector.
Since only the 3 metal pins are physically present inside the plastic connector, it is therefore impossible for it to connect and have any influence with your on-board computer.
We deliberately made the connector this way to prevent any possible damage to the cars computer.
If your dealer don't know what TripLogik is used for or how it works, they might think it is a device made to enhance the performance of your car, usually referred to as "Chipping" and will tell you it can void your warranty.
TripLogik is obviously not such a device, and since it is not electrically connected to the car computer, there is no way it can damage it.
If you dealer or mechanic still disagree, please have them contact us so we can provide them with more technical details and explanation.
