Hi, just got a 2026 Ram 2500 Laramie and want to install some extra lights that works with the highbeams, but it now seems like the headlights don't have highbeam signal power going to them, all done threw can bus now since 2025MY. Anybody found a way to activate a 12v relay when the high beams are on?

You're doing it wrong
Does your truck have the Vsim? Ifso that should have a HB relay output

Curious to see if the +25 are prewired like the 22 I have. Might be able to just buy the vsim
