The G4X 300ZLink Plug-In ECU supports several options for fitting of a IAT sensor. Either of the following options can be used:
1.IAT Through Expansion Connector - The expansion connector provides ground and temperature channels for the connection of an IAT sensor. Note spare An Volt channels can be used as temperature inputs when a pullup resistor (to +5V) is added.
2.IAT Through Fuel Temp Sensor - Wire the IAT sensor in place of the fuel temperature sensor. This is connected to An Temp 2.
