Hey guys I installed the vled triton v3 switchback front turn signals 6k white/Amber and I got everything to work properly except there is a "Dim" wire that needs to be tapped into the positive low beam headlight wire so that they aren't so bright when the headlights are on they'll dim to 10% of the output I guess. Right now they are too darn bright but I can't figure out which wire I'm suppose to tap this "dim" wire into to dim the marker/turn signal lights. If anyone would please help me figure out the color or the low beam wire on the headlights. Also which harnesss would be best (main harness going to truck, harness going into headlights that supply drls parking/turn signal and headlight or can I tap it to my opt 7 led bulb harness? I don't want to go tapping the wrong wire. Thank for the help

Thank for the link but I can't figure out which wire it would be for the positive low beam. As you can tell I'm not to knowledgeable when it comes to electrical. If anyone would be able to tell me the color wire I should tap into I'd greatly appreciate it.
