Interior Accessories for F1 Brake Light - Plug and Play Harness 4 PIN's Rear Fog 4th Brake Reverse Light PNP Compatible with Subaru WRX STI 2015-2021 VA

This harness was truly plug and play. My F1 light had 4 wires red, green, black and white. This harness colors matched the function for the light. So, I did not have to adjust rearrange any wires. It connected to my rear driver side light connector of my 2016 Impreza with no problem. This makes install easy

I bought this for a brake light I bought on ebay and the only difference with the way this is wired and the ebay light is the red and green wires are opposite! So if you run into the same issue that's it

If you are already installing the 4th brake light for your subie, you need this, just buy it. It will make your life so much easier and you won't have to cut into any of the stock wiring.Close to plug and play. Hardest part of installing this specific part is getting the tiny wires from the brake light to properly crimp into the harnesses.Just buy it.

Get plug and play, makes your life easy, no cutting into wiring. Live and learn.

This made install a breeze on my 21’ wrx brake light.

Product works as expected. However was missing a wire connector. Seller never answered my request

Works great if you listen to paper

If you want a quick and easy connection into your rear lighting system for your 4th brake light or whatever, this adapter makes the job much easier. Crimp connectors are included to connect whatever. Seems durable and the plug ins to your cars connectors are tight.

Plug and play install, really simple.
