Z31 Idle Control Wiring

Ok for those of you who have done the N/A to Turbo Swap on your Z31, Here is how to wire the idle controls for proper operation.

Items needed

  • 2 female spade connectors
  • Razor Knife
  • Crimper or Pliers
  • Extra Wire (might need)


  1. There is a 4 pin connector on the n/a harness that went to the N/A idle controls on the n/a motor (on the intake plenum, Drivers side)

  2. Take the N/A Connector off by unhooking the wires in the connector and plug them into the new turbo connector. (use a little pick to pull up on a tab to release the wire terminals)
  3. You only need to plug back in the two that go to the idle up solenoid
  4. The other 2 wires (black and blue) plug up to the idle control device, the black one goes to the "up and down | " pin and the blue one goes to the "side to side - " one
