" Several different options come to mind.
The easiest thing to do would be not to replace the wiring at all. If you were to swap the old CAS, throttle body, AFM, ignition coils, oil pressure sensor, coolant sensors, etc., from the old engine to the new, and install on it an alternator from a '94-'97 1.8L NA engine, then you could simply drop the engine in and run with all of the old wiring.
Of course, this would not be ideal, as the fuel and spark maps in your ECU are optimized for the lower-compression, poorer-flowing 1.6L engine. You would also loose VICS capability (I assume that the Euro NBs and the US NBs got this feature at the same time.)
At the extreme opposite end of the spectrum is installing the NB ECU, which would also entail installing most of the NB's wiring harness. This is a monumental task, given that you will need to create a hybrid of the new and old harnesses, mostly to deal with trivial and inconvenient things such as the headlights, speedometer, radio, etc.
A middle-ground approach would be to leave the majority of the old wiring harness in place, run a few extra wires and re-connectorize old wires with new connectors as needed to deal with things like VICS, alternator control, two extra injector channels, and so on, and install an aftermarket ECU such as a Megasquirt 3. Doing this will allow you to properly tune the NB engine and utilize its native wiring and sensors (separate crank and cam sensors, 4 injector channels, etc) without also needing to bring over the many trivial little sensors and actuators (mostly emissions-related) that would be needed to keep the NB's ECU happy.
