Tapping into Dome Light?

[Milkcow500]

Hey trying to install LEDs in my door handles and I got a quick question. I already have my footwell lights tapped into the wires in my driver side pillar, so how would I be wiring my LEDs?

How can I tap into the dome lights? Does anyone have any pics where these wires are and how I should be wiring all 4 LEDs into the dome lights? Thanks.
