Upgrading the headlights on a 2010 Audi Q5 can significantly enhance both the vehicle’s aesthetics and nighttime driving safety. Often, these upgrades, especially when involving different headlight models, require custom wiring solutions. This guide provides a step-by-step approach to creating your own headlight harness extensions, a crucial component for a seamless 2010 Audi Q5 headlight modification. While it might seem like a complex task, with patience and attention to detail, you can fabricate these extensions yourself.
Parts You’ll Need
To begin, gather the necessary components. Having all parts on hand will streamline the process and prevent interruptions. Here’s a comprehensive list:
- 1J0 973 737 (socket) – 2 pcs
- 1J0 973 837 (socket) – 2 pcs
- 000 979 225 E (fat wire with pin) – 5 pcs

Step-by-Step Guide
Follow these steps carefully to construct your headlight harness extensions for your 2010 Audi Q5.
1. Capping Unused Holes
The sockets have 14 holes in total, a mix of 6 large and 8 small. However, only 11 are utilized in this application. To prevent moisture and debris ingress, it’s essential to cap the 3 unused holes. Use the provided thin and fat caps for this purpose, ensuring a snug fit.
2. Preparing Wires
The wires come with pins pre-installed at both ends, which are typically the same type (male-male or female-female). For our harness extension, we need male-female pairs. Cut each wire in half and solder a male end to a female end to create these pairs. Consider cutting the wires into approximately three sections, as the extension doesn’t require excessive length.
Ensure all cables are neatly cut and organized for the next steps.
3. Adding Grommets
Slide the grommets onto each cut wire. These grommets are crucial for creating a watertight seal when the pins are inserted into the sockets, protecting the electrical connections in your 2010 Audi Q5 headlight system.
4. Heat Shrink Tubing Preparation
Before soldering the wire pairs, cut and slide a 3-inch piece of heat shrink tubing onto one end of each wire pair. This tubing will provide insulation and protection to the soldered joints.
5. Soldering Wires
Solder the wire pairs together, creating a robust and electrically sound connection. You will need to create 22 such pairs for the complete headlight harness extension.
6. Heat Shrinking
Position the heat shrink tubing over the soldered connections and use a heat gun to shrink the tubing. This process insulates the solder joints, providing mechanical strength and environmental protection, essential for the longevity of your 2010 Audi Q5 Headlights wiring.
7. Inserting Pins into Sockets
Now, insert the pins into the corresponding sockets. Ensure the grommets are positioned correctly, flush against the socket housing, to maintain the weather-resistant seal. Each pin location is numbered on the socket, simplifying the process of connecting matching wires (1 to 1, 2 to 2, and so on).
8. Final Harness Extension
After several hours of meticulous work, your headlight harness extensions should be complete. These extensions are now ready to facilitate the installation of your upgraded 2010 Audi Q5 headlights.
By following these steps, you can successfully create your own headlight harness extensions, making your 2010 Audi Q5 headlight upgrade project a reality. This DIY approach not only saves costs but also provides a deeper understanding of your vehicle’s electrical system.
