You bet!

[@js002003]

great informative vid. does leaving it plugged into the obd port drain the battery over time? should you unplug when the car is off?

[@speedhaus405]

Leaving plugged in will not affect the car.

[@MarquaytheGoat]

Will this void warranty?

[@okchaz6634]

No

[@northernillinoistrucksoutd462]
