Harmony Audio Compatible with Chevy Corvette 1984-1989 Single DIN

In this review the Harmony Audio Compatible with Chevy Corvette 1984-1989 Single DIN Stereo Harness Kit is evaluated for owners seeking a straightforward retrofit solution. The bottom line: this kit bundles a Metra 99-4544 dash conversion, Harmony wiring harness and a factory radio to aftermarket antenna adapter to simplify replacing a Corvette factory head unit with a Single DIN aftermarket stereo. It is best for DIYers who want to retain factory mounting features and avoid cutting factory wiring while preserving the dash fitment.

Key Features

• Complete kit: Includes a Metra 99-4544 multi-kit, a Harmony HA-7016771 wiring harness and an OEM antenna adapter so installers get all core parts in one purchase.
• Dash conversion: The Metra 99-4544 converts 2-shaft openings to a Single DIN using ABS faceplates and included bracket parts for a clean dash appearance.
• Factory bracket use: Designed to accept original equipment factory brackets or the included 02-4544 bracket kit for secure mounting without extra fabrication.
• Equalizer slot option: Offers a 1/2 in equalizer provision plate for installations that need the factory equalizer opening retained.
• Wiring harness compatibility: The Harmony HA-7016771 harness is tailored for select 1978-1993 GM and Chevrolet vehicles to simplify connection to aftermarket radios.

Who It's For

This kit is aimed at Corvette owners from the 1984 to 1989 model years who want to install a Single DIN aftermarket stereo while preserving factory mounting points and dash aesthetics. It suits experienced DIY installers and independent shops that prefer a bundled approach with a dedicated harness and antenna adapter included.

Those who should look elsewhere include owners of non-GM vehicles, or anyone needing a Double DIN conversion, as this package is explicitly for Single DIN retrofits and specific GM model years rather than universal or larger head units.

Pros & Cons

Pros

• Comes as a bundled solution with dash kit, wiring harness and antenna adapter to reduce parts sourcing time.
• Uses ABS faceplates and bracket hardware to produce a neat, factory-like finish in the dash opening.
• Wiring harness is vehicle-specific to simplify connections and preserve factory wiring integrity.

Cons

• Limited to Single DIN installations and specific GM/Chevrolet model years, so it is not suitable for Double DIN upgrades.
