WRXLink (1-2)

From factory, models supported by the G4X WRXLink (1-2) Plug-In ECU are not fitted with an IAT sensor. There are two options for connecting an IAT sensor to the ECU.

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 AFM – The factory AFM wiring can be used to install a IAT sensor, connect the IAT signal to the AFM signal wire and use a 1K external pull-up resistor. The IAT can then be set to use An Volt 2. See PCLink Help > Wiring Information > Input Signal Wiring > Analog Inputs > Using voltage channels with NTC sensors for more details.
