Head Unit ISO Harness Adapter for Land Rover Defender
Head Unit ISO Harness Adapter for Land Rover Defender
Upgrade your Defender’s audio system with ease using our premium ISO Harness Adapters. These adapters are designed to bridge the gap between your Land Rover’s factory wiring and the industry-standard ISO connections found on almost all modern aftermarket head units (Alpine, Pioneer, Kenwood, Sony, etc.).
Plug-and-Play Simplicity Avoid the hassle and permanent damage of cutting or splicing your vehicle's original wiring loom. These "plug-and-play" adapters ensure a clean, professional installation that can be easily reversed if you ever decide to return the vehicle to its factory specification.
Available Variants:
- Flat Pin Adapter: Specifically for 200Tdi and 300Tdi models equipped with the original factory radio-cassette player.
- Round Pin Adapter: Designed for Td5 models that were originally fitted with the factory CD/Radio head unit.
- Puma/Tdci Adapter: Engineered for later 2.2 Tdci (Puma) models (typically 2011/12 onwards) that utilize the large grey multi-plug connector.
Note: 2007–2011 2.4 Tdci models often featured factory ISO connections already. We recommend removing your current head unit to verify your connection type before ordering.
Key Features:
- Seamless Integration: Converts car-specific power and speaker connectors to universal ISO plugs.
- No Modifications Required: 100% plug-and-play design—no wire cutting, crimping, or soldering.
- High-Quality Construction: Durable heat-resistant connectors and flexible wiring for longevity in vibration-heavy environments.
- Wide Compatibility: Works with all major aftermarket stereo brands.
Technical Specifications:
- Application: Land Rover Defender 90 / 110 / 130
- Compatibility: 200Tdi, 300Tdi, Td5, and Tdci/Puma models.
Whether you are looking to add Bluetooth, DAB+, or modern smartphone integration, our ISO Harness Adapter is the essential first step for a stress-free stereo upgrade in your Defender.
