    Drl harness

    Posted by Troy on Dec 11th 2020

    Highly recommend!! Decided to go with Subiebros on this one due to the simplistic design. Was kinda of skeptical because I don’t run the usual diode dynamics c light everyone has, I have a custom sequential. And it works! Pretty easy install, only had trouble taking off the light connector and white retainers.

    Excellent quality

    Posted by Tyler Max on May 23rd 2020

    This was an easy install. Just wanted to pass along some tips for anyone looking into this. I had to make a tiny surgical incision on the right side of my stock fuse box cover so that the wire could easily make it out without being smashed and so the fuse box would close properly. Also recommend removing the extra fuses from the fuse box cover for an easier fit with the aftermarket piece. Also the fuse picker piece will no longer fit with this aftermarket piece so throw that in your middle console. Otherwise take your time and be careful.

    Patience is key!

    Cables are as sturdy as they come. Other harnesses I saw didn’t have the quality compared to this. I would definitely recommend doing this while you are installing your C-Lights as it is easier to get to the resistor to unplug the power to the OEM DRLs. The directions were easy to follow but definitely want to take your time while working in the new plugs. Also... I’m on an 18 WRX but the fuses never fully sat flush in the harness. I was worried for a bit but when I put the attafuse in it worked fine and no issues. Just a heads up! If you are adding this after your C-Light install, definitely remove the passenger side portion of the bumper to get to the DRL resistor. You’ll thank yourself later!

    C-Light DRL Harness

    Posted by Krout on Mar 17th 2018

    Had a similar product on my 15 STi and I wanted the same for my 15 Forester XT. Bought the harness with the additional acc wires to connect to my side vent LED DRL's that I had installed. The harness was a breeze to install and makes it look factory once its all said and done. Great product.

    Better Than OEM!

    What more can be said about this harness that hasn't been said already? Being an electronic installer previously, I can tell you that this harness is made better than OEM harnesses! All connection points are soldered and heat resistant mesh loom is used. Top knotch in my book! Thanks SubieBros!

    Top Quality, Aftermarket C-Lights needed

    Posted by SycsFinest on Apr 19th 2017

    The Harness is great. The quality is superb and the cables are long enough to route them appropriately. I used the extensions to hook-up the LED Fog Bezels and they worked out great. This harness does work with the limited LED C-lights however; I would recommend you go aftermarket if you are looking to use the C-lights as DRL. The OEM ones just are not bright enough.

    High Quality!

    Best DRL harness on the market. Simple install and high quality wiring that is well put together. Highly recommend if you're looking to upgrade your DRL lighting. Can easily be reversed to stock if needed as well.
