Ive been away for awhile and i dont have the means to test this
in the mean time I noticed something else weird. On the diagram for the mazdaspeed gen 1 the red wire says to plug into the ignition relay with the pin on the PCM being 1AY. When i look at my PCM layout 1AY is different. 1AY is +12V from ignition switch, PJB F69, 20A. I noticed that if i have the car in precrank and let the gauge be fully functional. Then i try to roll up my window on the driver side after it is all the way up i will throw a body control module engine error and the pump will start going off as long has i keep trying to roll the window up. WTF IS GOING ON! I tried connecting the red wire to the ignition relay but its not a 12v so i get no power at all on that wire. Take a look at this diagram is matches the one i have for my car
