Im very new here, and I could use some help.

I just ordered a Grom audio unit that I will be installing into my 2013 mustang base model. The unit is meant for Mustangs from 2006-2009 I think, but according to another thread on this message board a couple people got it working with mine.

The question I have, and that the others were not able to answer for me (though they were very nice and helpful with other questions) is if there is a wire I could splice in to behind the factory radio to power (12v) it with the accessory delay rather than constant power. I would like this unit to be powered on with the car, and stay on even when I turn the car off for ten minutes or until I open a door, much like the stereo and windows act now.

Like I said Im very new to all this and would appreciate any help on the matter.
