Stupid Question: how do I unplug the TSS harness for grill removal / FRAC install?

Ok folks. I’m feeling pretty dumb. First time working on my truck behind any panels.

I’m trying to remove the front grill to install my FRAC harness. I got the grill pulled off its clips, but I can’t pull it off entirely with the TSS harness plugged in. Removed the square panel, but I can’t seem to figure out how to unplug the harness. I don’t see any tabs. It doesn’t seem to pull apart. And I don’t want to apply to much force trying, for fear I’ll break it.

So what’s the magic trick for unplugging the harness?

Help an idiot out, please?

 

Not the greatest video, but it shows where, kinda. This guy didn't take the little access door off on the top of the grille. I remember doing it, but that was about 3 years ago.

for some cars, the connectors are really tight. You have to wear it out abit until they are easier to remove. The best way I find is, use a tiny micro flat head screw driver. The ones you use for small electronics, while pressing on the connected . if you pry in the middle where the tab is, it helps with the removal.
