Thank you all for weighing in on my issue. I had some time today to get under tha car and uncovered the following;
Starter is a Bosch model 0001312100 which I think is not a Porsche standard issue.
What I thought was terminal 50 on the starter is actually a thick ground lead to the starter body.
The yellow wire from the charging system going to relay 85 is dead when ignition is off and GROUND when ignition is ON.
Black wire going to relay 86 comes directly from the ignition.
I think that mreid is correct in his initial assessment that the green wire actuated the starter solenoid when the relay is actuated.
Thoughts before I try it?
