I'm a little late to the party, but that's how the Nissan side is wired from factory. All I did was show the Nissan side and Toyota side together so people would know what to do. If you follow it, the car will fire up, as long as you find the correct wires (there's are multiple same colour wires from memory).

You can just pull the three relays and wiring out of a s13 engine bay harness and fuse box and just hook up the white and black/orange wires from the Toyota side. I tucked mine up in the passenger's side wheel well along with the factory ke70 fusebox.
What's easier and nicer is to ditch the factory power system and ECU and make a fuse panel and get a vipec/link/haltech/adaptronic.
