New 2025 Tahoe Taillights

[PPV9c1]

When I removed the 2021 Tail light and compared it, the plugs were surely different. I went under the vehicle hoping that further below the harness would plug, but still no. I will try to post pictures in the upcoming days.

I’m sure they’ll fit with a custom harness. Back in the day I retrofitted 2018+ LED tail lights onto my 2016 F-150. I made custom harnesses for them. It was super easy to do thanks to very detailed instructions written up by member of the F150 forum. Someone here has the technical chops to do this. Now all we gotta do is sit and wait.

Did they otherwise fit in the space in your pre-‘25? (Is it just a matter of wiring up a compatible harness?)

Doubt it’s going to be plugn play. the light animation more than likely comes from the BCM, not the the light fixture.

What’s the animation anyway?

That’s fine. Them not doing that wouldn’t bother me in the slightest. The main thing here is the aesthetic.

We're talking tail lights here though. Do the tails do the exact same thing? And is that how the turn signals "blink" in the rear?
