Your Advantages with Our Legacy IV Wiring Kits

Vehicle-specific & plug-and-play: Harnesses and connectors are perfectly matched to the Legacy IV’s rear lights, bumper and body for a clean installation without modifications.
7- or 13-pin versions: A 7-pin kit covers standard lighting and signal functions. For reversing lights, accessory power or frequent trailer use, the 13-pin kit is the better choice.
LED-compatible & error-free: Supports modern LED lighting and LED retrofit options without warning codes or blinking issues.
Durable & weatherproof components: Weatherseals, corrosion-resistant materials and protected cable routing—especially in the rear and underbody—ensure long lifespan.
Standards-compliant & safe: All wiring kits are EU type-approved, TÜV-compliant and road legal—important especially when towing or using full feature variants.

Technical Notes & What to Check Before Purchase

Check your vehicle details: exact model year, engine type (e.g. 2.0i, 2.5i, turbo, etc.), trim level and lighting configuration.
Decide what extra functions you need: reversing light, constant power, trailer connector or accessory lighting.
Select the pin version: 7-pin for basic usage; 13-pin if more flexibility or towing capability is required.
Look for weatherproof connectors, reliable ground points and well-protected cable paths—especially important as vehicles age.
After installation, test all light & signal functions and ensure no warning messages appear on the dashboard.

FAQ – Frequently Asked Questions about Wiring Kits for Subaru Legacy IV
