No pin 3 on your maf connector. Do you have their sd cable? They plug right into their sd cable (below) except for the ground

The power connection (labeled “Vcc”) needs to run to a switched +12v source. You can find a convenient switched +12v source on the MAF connector harness. This will be a thick red wire on pin 4 of a 2G/EVO3 MAF connector.

The signal wire (labeled “Out”) needs to run to the ECU's MAF input. This is pin 3 (blue with yellow stripe) on a 2G/EVO3 MAF connector.
