I think this signal is the one going to the frequency valve on the fuel
distributor - it's duty cycle determines the mixture richness, so a dwell
meter can read it. The signal is developed from the control box in response
to what the O2 sensor tells it. (This from reading the Bentley manual months
ago, so I might be mistaken..)
