Just following up on my own inquiry. Tonight I tried to use the Chrysler CCD adapter from DS708 again with my MD802.
To my surprise I noticed that the end that plugs into a male 15pin cable has one of the posts that was slightly loose, therefore
not letting the cable make tight connection. I used needle nose pliers to screw both posts tight. After that I was able to successfully
scan 1999 Jeep Wrangler in native mode and read Airbag codes.
So it appears that the entire set of DS708 adapters is fully compatible with MD802.
Hope it helps the next person who runs into this issue.
good luck,
Max
