Quick question about illuminated door sills.

[Ganjie]

So I sourced a set of (still functioning) illuminated door sills. I have removed paneling to find that my car does not have the stock wiring harness for these. I was wondering if I should be tapping into the dome light or the door switch or a fuse? I purchased some add a circuit puse taps but cant seem to find any info for a 2017 fiesta st fuse panel (regarding doors or dome lights). Any info would be highly appreciated. Thanks in advanced!!

I do not believe there is a "stock" wiring harness for these - my recollection is that the interior/dome lights are controlled by the Body Control Module and as such there is no way to tap into the fuse directly. That's unfortunately all I know.
