-The power connection (labeled "Vcc") needs to run to a +12v source. You can find +12v either straight off the battery (of course) or there's a +12v wire on the MAF connector harness too. This will be a thick red wire on pin 3 of a 1G MAF connector or pin 4 of a 2G/EVO3 MAF connector.
+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 3 of a 1G MAF connector or 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 2 (green with blue stripe) on a 1G MAF connector or pin 3 (blue with yellow stripe) on a 2G/EVO3 MAF connector.

 So you would change the -40.5% global fuel to -56.2% before enabling the ethanol sensor adjustment in ECMLink.
