Hi, I am trying to find out why the SAFC installation write-up in the autoFAQ has the white airflow sensor wire spliced to the ECU and the picture shows the yellow wire not being used. If you look at the SAFC2 wiring diagram in the manual, you need to complete the circuit using the yellow wire as the out to the ECU input. Is this picture just wrong or is this faq incomplete, or is the wiring diagram by Apexi wrong? Or am i missing something :)
