2018 Sierra DRL


Cant Get Right

Been a awhile since I'v posted so quick update.

A few months ago I bought a new 2018 Sierra SLT premium plus, 4WD in cardinal red.
So far I'v done the basics: 2.5" zone leveling kit and 33x12.50r20 Gladiator X Comp M/Ts. Window tint, ect.

Has anyone messed with the LED DRLs on these trucks?
In particular, I'm trying to prevent them from dimming while the headlights or the fog lights are on.

During the day with no other lights on they are nice and bright, i'd like to keep them that way even when driving at night or while i'm using my fog lights during the day.

If not, I'll be pulling schematics and finding the easiest way to do this soon.
I'm unsure if this is as easy as the old diode jumper trick.
