Are you sure with 12 and 14, ... as these lead to the Acc. enrichment unit and AFAIK this includes Schmitt Trigger components, so for me this sounds like affecting the PWM signal where no constant voltage is present. Or am I on the wrong way?
Also 7 leads to the "15°C temp"/"35°Throttle" switches which simply lead to ground when cold or accelerating, which would cause a short circuit if voltage would be present on this wire on the side of the ECU.
