Is it possible to put a ty752 in a 2000 bug eye sti ty754
if so whats involved in the wiring

 

Works the other way around, but don`t know the way you suggest.
The wiring is plug and play, only the converter would need to be swapped from mechanical to electric by undoing one and replacing.
Me I`d change the rear diff with it, better safe than sorry.

 

As long as the final drive I'd the same it's a straight swap. If not u need to change rear diff, use the sensors from original box, and the wiring will not need changing
