Does the MD802 All systems DS truly support all 701, 702, 703, 704 functionality?  Can I use adapters designed for these systems to scan pre-obd cars?  There is zero documentation on this,  and I would like some more information.  Can I use a nissan 14 pin adapter to scan nissan consult 1, 2?  It says on autel website I can get nissan 14 pin as an accessory.   What about toyota pre obd? would this not be included in 701 functionality?  Can I use 701 or maxidas adapters?   are they the same?  

Where can I officially buy the accessories listed for an md802?   

This needs to be documented! My maxidiag elite md802 all systems DS box says PRE-OBD,  the website says accessories,  yet the manual mentions nothing? What am I missing? Need more information on these capabilities,  thank you.
