Hello,

I am planning on installing the Snow Performance Stage 2 MAF Water-Methanol injection kit to my 2012 Civic Si. There are 5 wires on the MAF sensor plug. Apparently, the FlashPro Manager help files indicate the two appropriate wires for the IAT sensor, but I am unable to locate the air flow signal wire. Of the 5 wires on the MAF sensor plug, which wire pertains to the 0-5V signal for the air flow? I need to spice into this wire to link to the water-meth controller.

Thank you.

Thank you.

according to my ECU pinout. On connector 'B' of the ECU pin #22 is a Light Blue wire, that is the 'AFM +side' and pin#43 on the same connector is the negative side and it is a Light Green wire.

The wires should be the same color on the AFM plug. Light Blue positive, Light Green is the negative.

Thank you, this is very handy info to have.
