    Headlight Wiring Instructions

    What’s up guys! Got a 2012 LT, about to install an aftermarket headlight assembly with DRLs, as well as fog lights that function as DRLs.

    As much as I’m a fan of trial and error, or using a multimeter to test the voltages of the headlight various wires to determine their identity, I’m also a fan of not pulling my hair out.

    So if anyone’s had any experience wiring DRLs on our lovely little car, could you simply tell me which color/position wire controls the Cruze’s existing DRLs so I can just splice into that? Or perhaps point me in the direction of a wiring diagram?

    Anything is appreciated!

    The stock DRLs are the headlights and they use a modulated signal to operate at a lower intensity. You would need some sort of smart relay (or pair of relays) that can read the different amp draws and react accordingly

    Ah I see what you mean. After looking into it further, it looks it might be simpler to splice into the sidemarker lights as some have done. Although I will admit I didn’t even realize they existed until just now lol
