165 Output Pin

[Mike Turner]

Does anyone know for sure which ecm connector pin is the cooling fan
actuator for the 1227165? I have three manuals, all with different
conflicting pinouts (D2, D12, C9,...???), and ecm which will not turn on
the fan. I'd like to try to repair the bad ecm and thought someone might
save me a few minutes of signal checking if they already knew the correct
answer. Car is 86 vette. : )
