If you get all three green relays with their wires attached, follow the S13 wiring diagram and work out what needs to be 12v permanent, 12v switched and negative etc. You can then identify the same on the 3 plugs by the S12 Maf. Have you worked out that you will also need to wire in a separate knock sensor wire as on the S12 its part of the engine loom, but not on the S13 one. I fed it from the connectors under the Maf round the slam panel and RH inner wing to the sensor.
