I'm assuming you mean high-port (early SR20DE in the US).  To my knowledge
you can't or shouldn't swap intake manifolds between high port and low
port.  I also thought that the low port SR20DE was US only.  Or perhaps
both are low port?

Can you tell us where that extra sensor is located on the original
engine?  I wonder if it's a temp sensor for emissions.

As for the harnesses being different, that's OK as long as you use all the
US sensors.  You may be correct that he may need to swap out the intake
manifold.  When I installed the DET there were only two connectors I didn't
use.  One was the EGT sensor for emissions that was never used outside CA
AFAIK, and one of the little emissions thingies that has all the vacuum
lines going to it under the TB.
