Defender ISO Harness Adapter

Land Rover Defender ISO Harness Adapters

Easily upgrade your Defender’s stereo with our ISO harness adapters. Designed to convert the original Land Rover radio wiring into the industry-standard ISO format, these ISO wiring harness adaptors provide a simple plug-and-play solution for fitting modern head units. No cutting or splicing required.

Available Options:

• Flat Pin ISO Harness – for 200 & 300Tdi Defenders (factory radio-cassette units)
• Round Pin ISO Adapter – for Td5 Defenders (factory CD/radio units)
• Puma ISO Harness – for later Tdci/Puma Defenders (2007 onwards with Alpine head units)

These ISO adaptors allow you to connect aftermarket head units, avoiding complex rewiring seamlessly. If your Defender has already had an aftermarket radio installed, you may already have ISO plugs fitted – simply remove the head unit to check.

Key Features:

• Converts Land Rover plugs to standard ISO radio harness connections
• Compatible with 200Tdi, 300Tdi, Td5, and Tdci/Puma Defender models
• Plug & play design – no wiring modifications needed
• Ideal for any Defender stereo upgrade
