I am trying to get a reading of my mass air flow meter(1993 240). My Haynes manual says to measure the ohmes between terminal #1 (yellow andgreen wire) and terminal #4 (red/white wire). The problem is that my yellow/green wire is on terminal #2 and red/white on terminal #3.
My guess is that I have to read #3 and #4, but I am not sure.
Any suggestions
