Okay thanks for the info. I'll talk with dealer and see if it in fact had it factory. I was thinking that too. Only reason I was convinced was when I ordered some that were Halogen only they never worked properly and had to return. The second set I acquired that were same as ones the PO put in were advertised as LED factory installion only and they worked Thanks again. I'll update when I find out.

Yeah, I test fitted it and it seemed to clip fine, I ended up trimming mine a bit with a dremel on slow with a sanding tip anyways. If you pause the video you can zoom in and read the SB and it states you "texhnician will have to trim part." So I just trimmed it. It did seem like the slot that should go on the outboard most flange of that crossbar it clips onto didn't really engage over the flange. So I just clipped it to engage fully on the white clip and tested it and it was fixed. So I just zip tied and called it done. Hope it helps

Hey, I was wondering if anyone has any luck finding aftermarket tailight replacements for the 2014 sierra 1500 with OEM factory LED tailights. Literally very very rare to find. Only ever find Halogen replacement. OR is there a way to fit the Halogen OEM setup into the truck?? I've looked everywhere. No straight answers. The problem I have is I bought the truck used in 2016 at 36k. The goof that had it before installed some aftermarket tailights that worked with LED factory harness, which I believe are these ones: https://www.tdotperformance.ca/products/spyder-automotive-5080707-led-tail-lights-black-smoke.html?gad_source=1&gad_campaignid=16186571898&gbraid=0AAAAAD1t1bWUgzQKgfKbn9BDfh-URpODA&gclid=Cj0KCQjw953DBhCyARIsANhIZoZzYyW4UlpMKUR-oso_Wagh_SW8lo3LMvtlENuPAXInfryh5Cdp_dsaAtTHEALw_wcB#2014-gmc-sierra_1500?utm_source=google&utm_medium=cpc&utm_campaign=ToF_Search_PerformanceMax_&utm_term=_ The resistors on PCBs rotted out and I managed to find the same ones at a wrecker 4 years later. Started with hyperflashing developing in high heat conditions. Well low an behold, the replacements I put in are doing the same now. I need a fix. Because tailights that fit factory LED are so hard to find I tried to see what it would take to change the truck over to OEM Halogen harness. Is it just a wiring harness?? Or does BCM need flashing aswell? I've called dealers and they want diagnostic fee.. Parts guy told me BCM needs flashing possibly but didn't know forsure. GM technical support says "We recommend you don't alter your vehicle from factory." thanks GM... Any help would be greatly appreciated. I'm at my wits end and I don't want hyperflashing anymore.

Checkout this video on you tube. After living with this for 10 years I can't believe it worked. Honestly.. and the best part is it's like a $6 part. https://youtu.be/J8O67RfvE5Y?si=C1YdVwI91yYmr2yQ #PIT5542: Front Seat Lateral Movement and/or Unable To Install Front Seat Lateral Retainer When Performing PI1376 Or PI1183 - (Jan 25, 2017)" For this fix you will need a flash light, zip tie, and GM Part Number 13405675.
