Hi everyone, I installed my LED headlights on my 2020 Silverado HD Custom, I purchased my headlights from a guy outside ebay but he was offering the headlights on ebay originally, I order the harness from gen5diy here is the link to order the harness https://www.gen5diy.com/collections/19-20-silverado-plug-play-harnesses/products/19-20-silverado-led-headlight-harness the only problem I found is that when you turn the signals does not turn off the day time running LED's like in the LTZ or the High Country ( but I think is not the relay is probably the configuration of the truck because it was not made for the Led's) But other than that they work great, I'm very happy with this upgrade to my truck.
How to do the install: I found a video from the guys at Frontier Truck Gear for how to remove the grill https://www.youtube.com/watch?v=kcHwBJZDTWI I did the installation in about an hour with the help of my brother
make sure to attach the relays to the body of the truck.
