Using this LED conversion harness is a breeze. First, if your truck is from 2014 to 2020 and you want to upgrade to the 2018 OEM LED headlights, these harnesses are perfect for you. They are plug - and - play, so you don't have to cut or modify the truck's factory wiring. If your truck doesn't have OEM LED DRL, choose the optional DRL power harness and connect it to a switched power source like the fuse box. The DRLs will then always be on at full intensity. When installing, keep in mind that because the new headlights use a different front turn signal bulb, you'll need to re - pin the connector from your truck. Swap the purple and black wires for the blinker to work properly. It's a good idea to use a Pin - Crimping Tool or Needle Nose Pliers for this. As for maintenance, since the harness is 100% stock wiring and unmodified, there's not much special maintenance required. Just make sure all connections are secure over time, and if you notice any issues, check the warranty as it comes with a 2 - year guarantee.
