No, all that will do is allow you to turn off the lights whenever the dome lite circuit is on. If you want to be able to turn them on independently, you will need to tap a wire with 12v on whenever the key is turned to on.
If you use a relay, then you can have both activation with dome light as well as toggling with a switch. Either way, if you want to switch it on with something other than the dome light switch, you'll need a 12v line. Luckily i believe there is at least one or two coming out of the BCM so it will not be any harder to tap than the grey wire.
