Thanks ctuna. Any idea what I can use as the source of accessory power so that the HU turns on when I plug in the key (and shuts off when I pop out the key) instead of having to start the car to have the HU to turn on. The instructions for the Metra harness said to connect that to the the ACC fuse but I am not sure where that is. Also, I read on the forums that all the fuses time out when the car goes into sleep mode. Is there any truth to that? If so, would the slot where the caraudiocraze DIY says to plug in the constant work since all of them will time out eventually?
