Headlights and Tailights RAM 1500 Limited 2025 on RAM Laramie 2025

[HelvecioFilho]

Hello everyone! I live in Brazil, and the only RAM 1500 sold here is the Laramie 3.0 ST trim. I bought a 2025 Night Edition. But the taillights and headlights are very weak. I took advantage of a trip to Florida and brought the Limited trim headlights and taillights for it. The taillights are installed, and all it needed was a constant positive pulse adjustment on one of the wires (I even saw this in another post from a colleague), and it worked 100%. Now, we're having trouble with the headlights. Everything worked plug and play, except for the high beams, where some colleagues here mentioned that the headlights probably receive a CAN bus pulse on the same high and low beam pin to connect, but the vehicle doesn't send the signal. To solve this, I would need to program the BCM module, but no one here has done that yet. Does anyone have any suggestions?

Not going to happen anytime soon. It's being worked on, but it takes an extra step after changes and that's not possible right now.

How did you wire the taillights? I’ve also been curious about the headlights. Does it throw any codes with it plugged in?
