I ordered a 2025 Tahoe LS Tail light from the local dealer. Unfortunately the plug/harness is completely different from the 2021-2024. It is a wider plug and to adapt to a 2021-2024, we will likely need a custom harness built.

That stinks. Well, maybe the aftermarket will start making good clones soon with pre-‘25 harnesses.

Thanks for sharing, sorry it didn’t work out for you (and all of us!)

It wouldn’t surprise me if the plug under the bumper/back of the truck is the same in the 25 as 21-24 and you just need the short harness that goes from there up to the tail light to get it to plug in. Note that there is a chance that you would need to add a resistor or two to compensate for LED vs incandescent bulbs used in 21-24 Tahoes & Suburbans.

I was thinking the same thing(s).
