Well the speedo, reverse lights, and neutral saftey switch. My car doesnt have cruise control so I dont have to worry about that. Also do I just reprogram the computer to a stick or what?

As far as I know,
The speedo from the 91 should be the same as your 89, just unplug from the A4 and plug it back in to the T5. For the reverse lights there is a connector on the left side of the transmission case, just hook the wires from the ??automatic shifter?? up to it. And for the neutral saftey switch some T5s have a neutral saftey switch in the top transmission case cover, but if yours dosent, you just reroute the wires from the again ??automatic shifter?? to the clutch pedal and install a switch so that the car wont start unless the clutch pedal is pushed. The T56 swap thread sticky tells how to wire some stuff. It starts on page 3 post 145. https://www.thirdgen.org/forums/tran...-thread-3.html. Hope this helps.
