This is what I meant this is what not working

Yeah DRL works well during daytime its bright, but what I know if you want to turn it on you can without turning on headlights and the "c" turns on dim. Like the original 2016 they have 3 selections 1-DRL 2- "C" on with the headlights 3- "C" only

Hello guys I have 2015 SLE and I bought the 2014/2015 Sierra NON SLT to 2016-2017 1/2 Ton SLT LED Headlight Harness from Gen5diy everything is working fine the only issue I faced is if I just want to turn on the "C" I cant it comes on with the whole headlight it doesn't work alone, the DRL works fine during the day but lets say at night I just want to turn on the "C" without the Headlights I cant, is there another harness! I talked to Jarod he said this how its designed!
