Land Rover Discovery Harness

The Metra 70-9400 wiring harness connects an aftermarket amplifier to the factory audio system in a Land Rover Discovery. It uses a vehicle-specific plug and four RCA connectors to deliver a clean pre-amp signal without cutting original wiring. The black finish matches typical dash surroundings.

Installers Adding an Amplifier

This harness suits installers who want to keep the factory head unit while adding external amplification. It is not for systems that require speaker-level inputs or vehicles other than the listed Discovery application. Buyers needing a different connector count or pin layout should verify compatibility before purchasing.

Four RCA Pre-Amp Outputs

The harness provides four RCA plugs to carry front, rear and subwoofer channels to the amplifier. This channel count determines whether the harness matches the amplifier's input requirements. Confirm the amp accepts four RCA pre-amp connections before installation.
