HKS3 V3.1 Wiring Diagram needed for 2015+Subaru WRX FA20 DIT
Hello Richard,
Is there a wiring diagram for the 2015+ WRX DIT ? I found the one for the HFS4 V3.1 but I want to be 100% sure the installation is correct. Another shop used the HFS4 V3.1 diagram thats found online to install but I cannot get the system to self trigger. Its also showing a open circuit for the boost solenoid so I assume they're trying to use the DHB failsafe function. Any help appreciated as usual. Cheers |

Can you post the wiring diagram used, could be an outdated one. Here is the latest:

Thank you Richard. Here is the diagram that the shop who installed the system used.
https://goo.gl/photos/RR3p6rWtMt1Wr6cn6 As you can see its V1 and missing the very important lower section of the diagram compared to what you posted. I did see the HFS4 thread you linked to but I was unsure if it applied exactly to the HFS3 V3.1 The car is throwing a trouble code for the wastegate solenoid being unplugged. the DR1 jumper was not installed and the prescaler jumpers were incorrectly configured. I went ahead and set those according to your posted diagram. Please advise |

Also check the Rail pressure and MAP sensor wires, they have also been revised.
