    The MAF wiring on the harness is identical for the Z31 MAF and Z32 MAF. There should have been zero changes to that aspect.

    The ECU needs resistors removed to deal with the modern MAF voltages, as the Z31 MAF functions from 1-7v rather than 0-5v.

    Yup, need to desolder the pin in the ECU. I could get my car to idle, but it would run like crap until I bent pin back.
