2 long wires (obviously)
I ran under header from dome light down behind A post & comes out under passenger footwell
Unplug the dome light & give yourself plenty of wire to work with
I soldiered each wire the the reverse of the domes bulb holder so on the outer side of the bulb holder (note what side is +)
Put the dome back in place BUT DONT connect the plug yet
gently take up the slack on wires
Now run a section of wire (taped in teaser) from passenger footwell to drivers give yourself plenty of cable just in case
Soldier your light wires to the wire and tape I’ve used soldier shrink & black teaser tape
Now tuck wire behind carpet or secure as you see fit
On the passenger side soldier shrink all wires together with light wires and teaser tape
Once wiring is completed and taped no risk of shorts .. plug dome back in open a door & voila!! You now have footwell lights that work the same as the dome
I used these

I have one in my dome & I retrofitted the other 2 for the foot wells by clipping off the attached faux bulb stripping the wires and connecting
They also have sticky backs so easy to place
You could probably use these too

However in my experience they work well in the boot but tend to pop leds when lit when the engine is running
