If you want to run closed loop idle,you'll need to disconnect the connector for the orange wire by the battery to reset the computer. The first time you start the engine,it will run with closed loop idle as long as the engine runs untill you turn the ignition switch off. The next time the engine is started,it will automatically operate with open loop idle. It first needs to learn how much fuel the engine needs to operate at 14.7/1 air fuel ratio. Once it knows this,it can calculate how much extra fuel to give the engine to smooth out the idle during open loop idle operation.
