I have a x930bt and cant find a wiring diagram. Head unit is installed and working fine but I am adding an amp and speakers and dont know what wire to connect "from the amp" which is called the "amp on" wire to the head unit.

I have an Arc Audio amp with a blue wire labeled "amp on" and I dont know what wire to connect it to on the back of my head unit.

A wiring diagram would be awesome if someone has that.

blue/white wire on the black HU power plug will turn on the amp, also called system remote control. hope it helps
