How to wire VPC and SAFC together
The VPC has the yellow wire that generates the air flow signal. The SAFC has an input and output wire. Connect the yellow output of the VPC to the input of the SAFC. Then connect the output of the SAFC to the fields harness wire that was originally the maf wire.
So you are taking the VPC signal, running it through the SAFC, then it goes on to the ECU.
