Sorry to ask, but I just want to be certain on this. So if I understand correctly I just need to take the 2 harness plugs out of the bottom of the N351 EAT unit and that's all? There is no replacement ECU for a manual car or do only the turbos use them? Sorry for the ignorance on this but I'm almost done and this is puzzling me lol.

 

You don't have to change any wiring inside the car for the manual conversion. [Unless it's an S5, then you need to disconnect the A/T computer]
