VW FAKRA Connector Types and Their Applications – Professional B2B Guide (2026)

Intro: The Colour‑Coded Backbone of VW Infotainment, GPS, and Cameras

FAKRA (Fachkreis Automobil) connectors are the standardised coaxial interface for automotive RF applications. In Volkswagen vehicles, they connect radio antennas, GPS modules, infotainment systems, and backup cameras. With up to 14 colour‑coded and mechanically keyed variants, FAKRA connectors prevent mismating and ensure reliable signal transmission in harsh automotive environments.

In this guide, you will learn:

• The different FAKRA types used in VW vehicles (A, B, C, and beyond)

• Their technical specifications (50Ω impedance, DC‑6 GHz, -40°C to +105°C)

• Applications in navigation, radio, cameras, and driver assistance systems

• Colour coding and how to identify the correct connector

• Why FAKRA remains the preferred choice for VW (vs. newer HFM connectors)

• Where to source high‑quality FAKRA connectors (LEADSIGN offers pre‑terminated cables)

1. Overview of FAKRA Connector Types Used in VW Vehicles

FAKRA connectors are standardised according to DIN 72594‑2. Each type has a unique colour and mechanical keying. The table below shows the most common types in VW vehicles:

Key insight: Colours are not decorative – a blue FAKRA C will not physically mate with an amber A. This prevents connecting a GPS antenna to a radio input.

2. Technical Specifications of FAKRA Connectors

Robustness: FAKRA connectors are designed to withstand vibration, temperature cycling, and moisture – essential for vehicle use.

3. Applications in VW Vehicles

🔹 GPS & Navigation Systems

• FAKRA types: C (signal blue) and H (erikaviolet)

• Role: Transmit antenna signal to navigation module or infotainment head unit.

• Why FAKRA: 50Ω impedance, stable phase, low loss.

🔹 Radio & Antenna Systems

• Passive antenna (no power): Type A (deep black)

• Active antenna (with phantom power): Type B (cream white)

• Diversity antenna (multiple inputs): Type K (curry yellow)

• Benefit: Clear AM/FM reception, even in weak signal areas.

🔹 Backup Cameras & Driver Assistance (ADAS)

• FAKRA type: Blue (type varies by manufacturer – VW often uses a specific blue‑coded FAKRA)

• Role: Carry AHD or LVDS video signal from rear camera to display.

• Important: Use pre‑terminated FAKRA cables (LEADSIGN) to avoid impedance mismatch.

🔹 Infotainment, Telematics, & Bluetooth

• Types: G (blue‑grey for remote control), others for WLAN, Bluetooth modules.

• Role: Antenna connection for keyless entry, tyre pressure monitoring, and telematics.

4. FAKRA vs. HFM (High‑Speed Mini FAKRA) – When to Upgrade

For most VW vehicles (pre‑2024), standard FAKRA is sufficient. Newer models with 4K surround cameras or 5G may use Mini FAKRA (HFM). LEADSIGN supplies both families.

5. Colour Coding – How to Avoid Installation Errors

• Never force a connector. If it does not click easily, the colour code is wrong.

• When replacing a damaged FAKRA cable: Note the colour of the old connector and order the same colour pre‑terminated cable (LEADSIGN offers all 14 colours).

• Common mistake: Using a blue FAKRA (video) for a GPS antenna (amber) – the antenna will not lock.

Tip: Keep a FAKRA colour chart in your workshop.

6. Tips for Selecting the Right FAKRA Connector for VW Vehicles

For high‑quality replacements: Use LEADSIGN pre‑terminated FAKRA cables – available in any colour, any length (0.3m – 20m), IP67 optional.
