The G4X RZR XP900 Plug-In ECU supports several options for fitting of an IAT sensor. Any one of the following options can be used:
1.Factory IAT – An Temp 2 is wired to the factory IAT sensor.
2.IAT Through Expansion Connector - The expansion connector provides ground and temperature channels for the connection of an IAT sensor. Wire the sensor between the Ground pin and an An Temp channel pin. Note spare An Volt channels can be used as temperature inputs when a pullup resistor (to +5V) is added.
