  1. Works with Non-WRX base Sedan

    By jham March 19, 2023

    Base Model 2015 Sedan has the same wiring in the back as WRX and so it was a quick plug in play. I got fat fingers so I actually didn't use the blue connecters and just used basic wire connecters but it was still convenient to have it pre-wired and just connected easily.

  2. SMOOTH, EASY INSTALL WHEN I INSTALLED MY OEM JDM REAR FOG LIGHT ON MY '21 STI

    By AL August 9, 2022

    Worth buying instead of hacking your factory harness.

  3. Sent Wrong Quick Disconnect Clips

    By Nick July 22, 2020

    I was sent male quick disconnect clips on both sides. I emailed their customer service department and was told I received the correct harness. When I sent a picture of the clips on both ends and how I needed female clips, I was advised to go to a local hardware store and buy the correct ones. It would’ve been nice if they would have sent the correct items in the first place or send me a replacement female clips. I won’t be shopping at subiespeed anymore.

  4. Def buy

    By Anthony November 2, 2018

    If you are buying the rear light, definitely get this too. Super easy to install and no splicing of wires.

  5. Quick and Easy

    By Thomas January 12, 2018

    I had ordered the quick connect harness to install the 4th light or rear fog light whichever you want to call it. I tried to use the quick connects that came with the product itself from iJDMtoy, but was a major flop. I ordered the quick connect harness not knowing if it would work and it did! It was the easiest thing on the planet. I highly recommend this harness as it puts your mind at ease knowing that you don't have to splice wires and if you mess up it's not a huge deal! Thank you Subispeed, can't wait to start buying more products!

  6. No brainer addition with the extra brake light

    By Nate November 4, 2017

    This made the install of my GCS light so easy. I personally don't like cutting/stripping/tapping wires, so this was totally worth the extra few dollars.

  7. Made it so easy!

    By Matt June 27, 2017

    Installing the F1 light was pretty tricky and tight with the wiring direct to the stock setup without the harness. With it, it was literally a snap!

  8. Simplifies F1 Light Install

    By Brendan June 26, 2017

    I gotbthis to install the Subispeed F1 Style rear fog light and it does the job perfectly. I didn't have to cut into any wiring, which was great. Definitely recommend. It is inexpensive and prevents damage to any wires.

  9. Well worth the price!!

    By Brett June 14, 2017

    If your installing a 4th brake light, this is a must. No cutting and splicing of oem body harness. And sped up install! Great quality and shipping is alway fast!

  10. Good connector

    By Kyle May 5, 2017

    So I purchased this harness for my '12 WRX with OEM rear fog lamp. The connector plugged inline with my vehicle but the wiring was not exact, so after re-pinning the harness I have my rear fog working and didn't have to splice any wires. So if you are feel up to moving some wires around in the connector you can make this work on previous generation.
