Yes there is a difference but you can modify the N/A harness to work. You will still need a turbo ECU though.

Check out this tech article that mavisky wrote: http://www.dsmtuners.com/forums/articles-engine-fuel/37019-installing-turbo-4g63-into-nt-4g63.html

what you'll need to wire in:

7th wire from mas - the 7th wire from the mas needs to be run back to pin number 6

knock sensor - one wire can be grounded to the engine bay somehow, the other white wire needs to be run back to pin number 9 on the ecu.

wastegate solenoid - one wire here will be grounded, the other returns to the ecu at pin number 105

injector resistance pack - this is the most dificult. i'll let the following pictures describe it rather than trying to explain it in text. if you have any questions just ask.

And here is a tech article by TimG on how to wire the injector resister pack on a 1g n/t harness: http://www.dsmtuners.com/forums/articles-electrical-wiring/174314-injector-resistor-pack-wiring-1g-n-t-turbo-conversion.html

Hope this helps!
