Illuminated door sills on a 2017 fiesta st

[Ganjie]

Essentially I'm looking for a wiring diagram or the which wire to tap into so when my car unlocks or when my door opens the sills illuminate. I read somewhere to tap a green/purple and yellow/Grey but I don't think that hloom exists on the usdm fiesta sts. Any help is very much appreciated.

As long as you're not overloading the wire, should be able to tie them in with the dome light circuit. Definitely post photos if you go through with this. Should look quite nice at night.

If there's any potential that you'll overload a wire/circuit, you'll need to add a relay. Swapping out existing incandescent filament bulbs with LED will lower demand on a given lighting circuit, possibly allowing more headroom for additions.
