Where to Connect the ACC Wire for Daytime Running Lights?
2 Answers
The ACC wire for daytime running lights can be connected to the middle terminal of the fuel pump relay in the engine compartment fuse box. More information about daytime running lights is as follows: 1. Daytime running lights, also known as daytime running lamps, are installed on both sides of the front end to signal the presence of the vehicle during the day. 2. Daytime running lights are not illumination lights but signal lights. Their purpose is to make the vehicle more noticeable during daytime driving. 3. The goal of daytime running lights is to enhance traffic safety. Therefore, many countries have established relevant standards for daytime running lights in recent years to ensure that the installed lights effectively contribute to safety.
The ACC wire for daytime running lights is generally connected to the fuse position in the car's fuse box specifically marked as ACC or accessory. This is how I did it when using an installation kit. The ACC wire only receives power when the ignition switch is turned to ACC or ON, allowing the daytime running lights to automatically illuminate when the vehicle starts, enhancing daytime driving safety. The operation is quite simple: First, remove the fuse box cover under the glove compartment, then use a test pen or multimeter to test each fuse one by one. The fuse that lights up when the key is turned is confirmed as the ACC point. Then, insert a fuse tap and securely connect the positive wire of the light to it. Never randomly connect it to the battery positive terminal or engine wires, as this could cause a short circuit, fire, or drain the battery. During my DIY, I once encountered loose wiring that caused the lights to malfunction, but switching to heat shrink tubing for sealing fixed the issue. If you're unsure, I recommend following the vehicle manual or video tutorials step by step—don't aim for perfection on the first try; safety comes first. After the modification, I felt more visible on the road with fewer accidents, but don't rely solely on the lights—regular maintenance of the headlight system is still essential.
