Advice on wiring 2017+ vertical DRL?

[Bumble_BRZ]

How should I go about wiring the vertical DRLs to have the same functionality as the boomerangs day/night? (ie. off when handbrake up during day, on as accent light at night)

I looked at the wiring diagram and checked the HLP harness with a multimeter but am unsure of what (if any) wire I should splice into.



The DRL wire (obviously) only has power during daylight but the boomerangs illuminate during night with the power coming from the lo-beam wire (stalk set to auto) or sidemarker wire (stalk set to parking)

It doesn't make sense to me that they would switch the power wire for the boomerangs based on headlights on / off.


There's quite a few threads here with the pinouts or it could be worth reaching out to a mfg that makes headlights for your car and asking them for the OEM pinout as I know some need pin swaps to make their headlights work.
