No pictures, but it is pretty easy to find. I didn't even use any ramps, the rear end is high enough to slide under, although a set of ramps would make it 10 times easier!! Anyway, the plug is located on the front end of the diff. on the driver side about 6 inches above the bottom. You can't miss it if you crawl under there.

 

Yep, it's been located there for the past 20 years ever since the 8.8"s were used
