This cirket is on a slow blow 45 amp fuse so you should protect your A/V with appropriate protection
If you don't work it out tomorrow I will have a little more time and can check it out for you.

The circuit suggested above is that which supplies fuse No. 3.
N.B. For very good reason I have suggested that you should pick up your supply subsequent to fuse No. 3.
A wire to your sub board added as suggested above, would provide a short circuit opportunity in respect of 45 amp main fuse No. 4. The OEM set up wisely separately protects each circuit subsequent to this fuse for safety reasons. In the event that fuse No. 5 blows, the main ignition circuit is interrupted, and motive power is lost, together with headlights. Not good in many circumstances.
If necessary Fuse No. 3, can be upgraded to say 20 amps, in order to cope with an added load, and adequate protection would remain in place.
