This is incorrect. The timing is advanced by the EEC.
There is NO, repeat, NO vacuum line to the distributor. That is old technology.

Yep, yellow wire (if still factory condition).
Unplug it, set it to 10*, shut off the car and replug it. The SPOUT takes the signal to the EEC out of the picture, To quantify if the SPOUT connection is getting a signal to the EEC, look at the timing again after it is plugged in. It should be more advanced now at around 25-30*.
