Aftermarket Ambient Lighting

[grocerybag420]

I am planning to install an aftermarket wireless ambient lighting kit into my 2017 Toyota Yaris. I am aware that I need to tap into the electric windows for the doors to get power to the led strips and the 12v cigarette port for the dashboard. However my rear windows are manual and not electric and therefore I would need to get the power from somewhere else such as the cigarette port. I wanted to know how I can do this and what wires I would need to use as the LED strip wires are too short to be wired from the front to the rear doors.
