Need help with interior LED Strip lighting.

My wife bought me some rbg led strips for the footwells and under the seats but I'm uncertain as to how exactly I'm going to power them.

Only thing I do know I need is a constant 12v feed that doesn't turn on or off (unless vehicle is off).

If anyone has already done this or knows where this constant 12v wire is, I'd greatly appreciate your help! Thanks!

 

Here is a diagram that came with the kit.

 

My first thoughts was to tap into the positive going to the cigarette lighters and power points but I'm not sure where that is or if there is a dedicated wire somewhere already for an accessory like this.

 

I have almost the same setup. I ended up using the 12V in the center console as my LED unit came with a switch that fit that spot with no modification. If I leave the switch on, the lights turn on with the ignition. The control box is hidden under the center console area and the wires are routed to under the seats and under the dash from there.
