I'm removing the (front) seat belt tensioners on m y 2001 XK8 convertible, and I'm baffled by this connector. (Almost all of my DIY experience has been with GM, Mazda and Mini Coopers, and I can't figure out how to unlatch this one.)

I'm reluctant to pull too hard on this one, because I'm not sure where exactly it comes apart, and I really don't want to break it. I moved the yellow "slider" to the alternate position, but then what? Pinch? Pry? Pull? Twist?

 

Ok, I figured it out (but not the Forum's "delete" function yet).
Anway, you slide the yellow slider, then simultaneously press a tiny black plastic square on each side of the connector where the yellow tab was originally. (The second tab, closest to the fabric of the seat belt, cannot be seen…only felt).
As you were...

 

I've moved your thread from General Tech Help to XK8/XKR forum. This is the place to post tech questions about your model.
