I have a gen 4 with stock quads. Just got my amber LED marker lights that I am incorporating 4 into the grill. Custom make a wire loom that will go towards the driver headlight assembly and tie into the driver marker bulb. This way they'll act just like the marker lights, on when they're on, off when they're not. I figure with the low draw of the LED's, it won't effect much of that circuit. Staying away from headlight/turn/DRL harness so there is no unforseen issues popping up from tapping into that source. Good luck, these RAM's look awesome with the LED grill lights...
