To get a Lambda computer or not? '87 engine

[laughac]

I'm looking at the 930 engine before install and wondering about the "Frequency valve" question.

Should I just buy what belongs on the other side of this plug?

Can someone show me a picture of it?
I'll show you my pic in a minute.

That whole deal plugs into a harness that runs to under the drivers seat. I think if you review this thread you have several options besides trying to find all that stuff for your car.
