MAF (HFM) wiring for Snow meth kit
 

I'm installing a Snow Performance Stage II MAF water/meth kit on my DASC'd Z3. I'm trying to find which of the four wires running to the MAF (HFM) is the signal wire. I'm 99% sure that the wire colors on the 318ti MAF wiring harness are the same as my Z3 as they share the same motor, DME, etc.

The wire colors are:
1. Brown
2. Red with white stripe
3. White with violet stripe
4. White with blue stripe

Does anyone know which of these is the 0-5 volt MAF signal wire?

Thanks,
Christian

Wiring is Grey/violet Signal, Grey/Blue Sig ground. You want the violet wire or pin 45 on the DME

Thanks John!

No problem. Hey keep it real light on the injection of Meth. It will hurt performance with too big of a shot
