Default Ignition Switch Wire from the Fuse Box

I am partially deaf and place my radar detector to the bottom left of the windshield. I would like to hard-wire it, the fuse box is the closest attachment point but the fuse box cover will not fit with a fuse tap. Does any one know the color/pinning of an ignition switch wire coming from the fuse box? Specifically the radio1 wire (7.5 fuse, second in the diagram) would be great. Thanks

The cig.-lighter/acc plug is switched also and some what easy to access. The nice thing is that anything you connect to it will correctly go through the acc. fuse.

As soon as BeatSonic mails a harness for an Alpine, I will be putting a video bypass and swi-jack on the cig plug. So I am not sure about adding another device to that list of consumption along with the usage of a cell charger. The bypass box I use does better away from the radio power source, don't know why but it does - guess timing. The aux plug powers two dvd headrest for the kids; both of which have dvds and screens, so I did not want to add there.
In my ES I used a fuse tap for the same fuse but there is no cover, it is hidden behind a coin tray; so everything worked out well and I was hoping to do the same.

Found a pdf of the radio wiring diagram. Have not tested it yet but it seems good.
