S15 Na to S13 immobiliser.

[Taipan 0]

I purchased a NA S15 engine without a ECU or Immobiliser attached to the harness to install into my S13 am I going need a wiring loom without the immobiliser plug to use a S15 Nistune ECU or can I use the AUD loom with the immobiliser plug without any dramas?

Thanks in advance.

 

Any links to wiring diagrams and guides would also be appreciated.

Not sure if this helps but I've got a S15 (200sx) and when I got my Nistune fitted I was informed that the factory NATS security has to be deleted from the ecu.
