Identifying The Reversing Light Power Supply Cable In The Harness\loom On A 2017 VW Golf MK7
Introduction
When working on the electrical system of a 2017 VW Golf MK7, it's essential to identify the power supply cable for the reversing light accurately. This cable is responsible for powering the reversing light, which is a critical safety feature that alerts pedestrians and other road users when the vehicle is reversing. In this article, we'll guide you through the process of identifying the reversing light power supply cable in the harness/loom on a 2017 VW Golf MK7.
Understanding the Wiring Harness/Loom
The wiring harness/loom on a 2017 VW Golf MK7 is a complex network of electrical cables and connectors that supply power to various components, including the reversing light. The harness/loom is designed to be modular, with different sections dedicated to specific systems, such as the engine, transmission, and electrical systems. To identify the reversing light power supply cable, you'll need to locate the section of the harness/loom that corresponds to the rear cabin space.
Locating the Reversing Light Power Supply Cable
To identify the reversing light power supply cable, follow these steps:
- Access the Boot Space: Start by accessing the boot space of the 2017 VW Golf MK7. You'll need to remove the trim panels and any other obstructions to access the wiring harness/loom.
- Identify the Rear Cabin Space Section: Once you've accessed the boot space, locate the section of the harness/loom that corresponds to the rear cabin space. This section will typically be marked with a label or a color-coded connector.
- Look for the Reversing Light Connector: Within the rear cabin space section, look for the connector that corresponds to the reversing light. This connector will typically be labeled as "R" or "Reverse" and will be connected to the reversing light switch.
- Identify the Power Supply Cable: Once you've located the reversing light connector, look for the power supply cable that connects to it. This cable will typically be a thicker gauge wire than the other cables in the harness/loom and will be colored to match the reversing light connector.
Visual Identification
In some cases, it may be possible to visually identify the reversing light power supply cable without accessing the wiring harness/loom. Here are some tips to help you visually identify the cable:
- Color Coding: The reversing light power supply cable will typically be colored to match the reversing light connector. Look for a cable with a similar color to the connector.
- Connector Type: The reversing light power supply cable will typically be connected to a specific type of connector, such as a 2-pin or 3-pin connector. Look for a cable with a connector that matches the reversing light connector.
- Cable Gauge: The reversing light power supply cable will typically be a thicker gauge wire than the other cables in the harness/loom. Look for a cable with a thicker gauge than the other cables.
Additional Tips
Here are some additional tips to help you identify the reversing light power supply cable:
- Consult the Owner's Manual: Consult the owner's manual for your 2017 VW Golf MK7 to see if it provides any information on the reversing light power supply cable.
- Use a Wiring Diagram: Use a wiring diagram for your 2017 VW Golf MK7 to help you identify the reversing light power supply cable.
- Seek Professional Help: If you're not comfortable identifying the reversing light power supply cable yourself, consider seeking the help of a professional mechanic or electrician.
