I wonder if I should have tapped the first connection (red wire of FAST) to head unit yellow wire for battery? So my above post would be incorrect in that I am not tapped into constant battery, but ACC/turn on wire. Can this cause any problems? Everything is working fine and sounds good for now.
No, it will not cause any problems. I personally still like connecting the constant power of the Tube to the constant power of the headunit. If you have any reservations about how the Tube is wired now, just connect the red wire of the FAST-9999 to the yellow wire of the headunit and keep on rocking.
