Yes, I have. It doesn't work as you hope. Once you plug in the add-a-fuse, the DRL circuit in the fuse box keeps the Raptor lights on, always - even with the truck off and you switch the lights off. The DRL circuit is powered through a relay instead of a normal circuit. You have to tap the wires going to the DRL near the headlight assembly for the Raptor lights to turn on when the DRLs are on. I add(ed)-a-fuse into the INJ circuit for my raptor lights, so when the truck comes on, the Raptor lights turn on as well. I may end up tapping the DRL circuit and the headlight circuit in the future, because I want the Raptor lights to stay on when I get out of the truck and the engine is off, but turn off with the lights.
I got this info from KY_Rob on TW: "after some digging, if found out why your lights stayed on when you tapped the 10A DRL fuse. It looks to be a constant power fuse, that feeds the DRL relay. When the ECU wants the DRLs on, it sends voltage to the DRL relay, which turns on. Diagram below: "
