Wiring Assistance for Running Board LEDs

[Korazu]

Hello, I purchased some turn & running amber lights with a courtesy light function. I understand that the white courtesy wire will plug into the grey wire at pin 23, which is the dome light, but can someone tell me what wires I would hijack to get the turn signal and running amber light from the block underneath the driver side? Thank you.
