Regardless which region it may be, there are very few single wire connections in that harness. I don't recall if the "Euro" stuff had a narrowband O2 sensor, but that would be one. The oil pressure sensor is another (not it in this case, though). Aside from that you typically only have single wire connections to ground, as all the other sensors are 2 or 3 wire. It could be a pass-though for power for another harness, but I'm not an expert on the first gen harnesses.
If you have the harness in hand you can either trace it back to the ECU plug and see what pin it is on (or what other wires it may T in to). You could also use a ohm meter/volt meter to do the same. Once you know the ECU (or relay box) pin location it will be a drop in the bucket to figure it out from there.
Attack life... it's going to kill you anyway.
