Description
xOverview
Oyviny’s Custom 4 Pin Trailer Wiring Harness is designed for select Subaru models equipped with a factory tow package. It delivers a clean 4‑way flat output so your trailer lights, brake signals, and turn indicators stay in sync with your vehicle on every trip.
The powered module draws from the vehicle battery, helping prevent overload on delicate electrical circuits while providing steady illumination for your trailer. With 14 AWG copper power and ground wires, this harness emphasizes reliable conductivity and reduced voltage drop, even on longer towing runs.
Key Features
- Plug and play installation using the existing OEM connector—no cutting or splicing required.
- Powered module connected to the battery helps prevent overload and minimizes electrical noise on the vehicle side.
- 14 AWG copper wires improve conductivity for consistent trailer lighting.
- Dust cover protects the 4‑way flat connector and fuse, reducing exposure to dust and moisture.
- Standard 4‑way connector supports tail lights, brake signals, and turn indicators for a wide range of trailers.
Compatibility and Range
This harness replaces the 56040 wiring and includes a tail light converter for Subaru compatibility. It fits Forester models from 2009–2024, Outback from 2010–2024, Crosstrek from 2016–2024, Ascent from 2019–2024, and related XV Crosstrek years. Please check the model year reference in the listing to confirm your exact fitment.
Real World Use
- Great for weekend road trips or camping when you need reliable trailer signaling on long drives.
- Ideal for towing a boat, trailer, or bike rack where synchronized lighting improves visibility and communication on the road.
- Durable design performs well in dusty or damp environments thanks to the dust cover and copper wiring.
Durability and Quality
Built to last, the harness uses pure copper conductors and a rugged 4‑way connector. The integrated fuse protects both trailer and vehicle circuits while the dust cover minimizes contamination during storage or use. Always verify fitment against your vehicle’s specification before purchasing.
