No electronics should be required. You wont have converter lockup however. You'll have to get a TV cable setup and install or properly making sure to set the line pressure correctly. If you search here or on google you'll find plenty of instructions. Search for TV cable and 700r4 and you'll get pictures of what you need. You'll also need to configure your shifter or get another shifter to be able to select the full range of gears (as it has one more gear than the th-350).
Guides say to shorten the drive shaft 3 inches. Mine measured to be 3.5. I split the difference when I did the conversion. Since its a slip yoke you have a little room for error.
