Notes

• Check that your connector matches the header shown in the photos before ordering. USDM 2011-2014 and 2015-2021 STI cars use the USDM WRX11X (243-4000).
• An air temperature sensor is strongly recommended.
• The security/immobiliser lamp may stay on in some models.
• The older CANPCB cable is not compatible; connect CAN devices with the CANJST4 (101-0198).
• Not for use where it would interfere with a vehicle's safety or emission control features. Link recommends installation and setup by an official Link dealer.
