RE: 4ks OXS-system connector problem?

If I understand what you're describing correctly, you'll find no
matching connector.
That is a test tap, used to read the duty cycle (dwell?) of the OXS
sensor.  This
connector provides a means to set fuel mixture, usually set in
conjunction with
ignition timing...
