There was an exhaustive thread from earlier this year on that topic. I can’t think of keywords to find it just now.

There are no distinct high beam fuses since the high beams double as DRLs. The 20amp DRL fuse suggests it might also be the high beam fuse but unusable as a high beam trigger.

What I recall is the driver side high beam gets 12V for DRL and high beam. The passenger side high beam gets 12V only for high beam. That’s potentially the LED trigger. It’s a red wire with yellow stripe. There’s a risk that in DRL mode there might be bough back voltage to close the LED relay. One way to find out :/ Alternatively, pin 1 or DRL relays 3 and 4 carry the high beam signal but rooting for wires under the fuse box is unappealing to me.
