    Default Winfred: a coolant sensor question..

    Apparently the one I tapped "pin 78* is 0v - 5v reading... whereas the megasquirt wants a resistive type sensor. So, the Pin 78 one is at hte ECU, which is electronic signal to the ECU, while I think the megasquirt wants the kind of reading that goes to the coolant temp gauge on the cluster. Where can I tap that signal? Where does the wire to the cluster meet up in the engine bay? Any idea on color? 9/91 build date M50 non vanos 525i manual.
