There is no 'standard' ecu. There are a couple of threads you easily find on VWVortex on doing a auto to manual swap. Essentially, you throw the auto in the scrap bin along with the tic, install a clutch, pedal, and transmission. Then you will have to wire in the reverse lights, clutch safety switch(for starting), and the clutch up switch for the cruise control. I just finished doing a swap last month, I find it is helpful if you keep you donor car around until the job is complete. Keep in mind, this is an EXTREMELY abbreviated synopsis of the process. The write-ups in vortex are excellent.
