Fuse 42 under the hood is the rear wiper. You can use an add-a-fuse here for DRL's. It's hot only with ignition. This is where I have mine wired to.On the kit with the driving lights it says about hooking up the terminals on the drls with the black wire going to the negative side of the battery and the red wire going to the ignition fuse box. im not sure if you are supposed to hook it in to a specific fuse that has hot all the time or not. seems kinda weird but i could always splice them in with the parking lights which would look nice since i already have leds bulbs in the parking lights looks a hell of alot more high end than the stock yellow bulbs.
