here's a good website that has a wiring diagram, as well as ECU pinouts. If you look at the wiring diagram, it's for a 200sx, with the drop in resistors at the injectors. I've been told that that's not the right diagram, but all the colors seem to match up in the chart, they just go to the wrong ecu pins. look for the power transistor unit (that's the ignitor)
