4age silvertop wiring and conversion to MAP

For those people who want to the AFM sensor and to use MAP sensor but want to retain original wiring, you may refer to this diagram. I have labeled all the input and output at the ecu.

This is ecu diagram from 4age20v silvertop

And this is comparison between blacktop and silvertop ecu pinout. You might re-pin or made a converter to use a blacktop ecu into silvertop wiring.
