What are the wiring steps for installing daytime running lights on a car?

The wiring steps for installing daytime running lights on a car are: 1. Locate the ACC position at the bottom left of the steering wheel; 2. Secure the daytime running lights in the appropriate position; 3. Connect the black ground wire to the negative terminal of the battery, the red wire to the ACC relay, the two white wires to the headlight fuse, and the two yellow wires or one yellow and one green wire to the positive terminal of the turn signal; 4. After installing the wiring harness, recheck for any loose connections. The precautions for wiring the ACC power supply for daytime running lights are: 1. The wiring should be covered with corrugated tubing; 2. Seal the engine compartment and connection points with tape to prevent leakage or water ingress, reducing safety hazards.
I've thought about installing daytime running lights (DRLs) several times, and it all starts with preparing the right tools. First, you need to purchase a proper DRL kit—opt for waterproof LED models. Then, gather essential tools like wire strippers, a multimeter, and insulating tape. Before starting, always remember to disconnect the negative terminal of the battery—safety first! When wiring, focus on two key points: connect the positive wire to the ACC fuse in the engine compartment fuse box (test for power by turning the key to the ON position), and attach the negative wire to a metal frame screw on the car body. Use a multimeter to check connectivity, and route the wiring harness discreetly, avoiding the exhaust pipe and belt pulley. Don’t rush to reassemble the housing after wiring—first, start the engine to test the lights. Once confirmed working, secure the wiring with zip ties and reconnect the battery. The most critical step is ensuring all contact points are tightly wrapped with insulating tape—I learned the hard way that poor connections can lead to short circuits in rainy weather, which is a real headache.
