any 2.7tt swap into 96 a4 btdt?

[spectrum]

Hi gang, looking for some insight from the collective wisdom.
I've got a 96 a4 with a gaping hole wherethe 1.8t used to live and next to it on the floor is a complete 2.7tt with harness and ecu pulled from a 2002 a6 6spd.
My biggest curiosity is the dbw throttle on the 2.7 vs the standard cable throttle on the 1.8t 
Swap the pedal cluster to that from an s4?
Any ideas on how much of the interior harness needs to change to mate with the engine harness?
Insturment cluster?
 
anyone have any ideas on converting the 2.7 to standard cable type throttle body and making it work with the stock ecu?
 
wish me luck,
 
Todd
