If you follow the instructions on the phastek site the gray wire that you tap into will control your LRDs from the dome light switch. My install was one Led strip that terminated on passenger side. When you unlock the doors the LEDs come on with the dome light and will fade normally with the dome light. If you use dome switch to turn off the dome light the LEDs also turn off or you can have both turn on using dome switch. Hope this helps.
This pic shows the passenger side where you tap into the gray wire be sure to check the voltage drop as that wire is the one you tap into. There are two gray wires in this wire bundle.
