i'm assuming this is all hooked up to the factory headunit right? just wanted to make sure.
i'm not a fan of using fuse taps, but if you want to, try number 28 or 29. those two look like they are ign powered. i would personally recommend doing an inline fuse and tapping on to the acc wire from the ignition.
