Frankielozano214 Posted October 11 Share Posted October 11 (edited) Just bought a set of 2024 Sierra 2500 HD taillights was wondering if anybody on here has done this conversion yet, the plugs are different and I don’t have the harness to the 2024 lights. I have talked to a guy that sells an adapter to make them work with the 2023 harness but it’s like 300$ will keep yall posted on this, (will be selling these once I buy a set of 2024 AT4 2500 HD taillights looking for the ones with the clear lens ) also selling my factory LED Denali/SLT taillights too Edited October 11 by Frankielozano214 Quote Link to comment Share on other sites More sharing options...

Frankielozano214 Posted Tuesday at 11:28 PM Author Share Posted Tuesday at 11:28 PM Finally got them installed yes they fit without modification, so have a minor issue when turn signals are on and pressing the brake they start to hyperflash, when I release the brake ped they flash normal. Dude is gonna check his wiring and check my wires via the vin from my truck and let me know something here tomorrow hopefully Quote Link to comment Share on other sites More sharing options...
