I'm assuming to need to find a parking light wire, yes? You want the lights to turn on if the parking lights are on. If this is the case, you can grab the signal at the BCM under the dash:
Parking Lights+ white/brown (LF); white/orange (RF) + BCM, black 24 pin plug (A), pin 4; white 24 pin plug (D), pin 3
The parking light wire at the switch is a MUX wire = not ideal to tap into. Since you just need a signal You can grab either the white/brown or white/orange at the BCM to turn on the lights. Make sure to test your wires before blindly tapping in as always.
