I purchased this bluetooth module to try and clean up the interior of my car, I've wired the power into pin #9 which is "12v Dir". Currently the module does not seem to power down at all from what I can tell even with the car off, but it works fine. Should the power be wired in the pin ##5 which is "12v acc" to make it power up and down with the car? Or should could I run the power to the cigarette lighter as a better option?
