Hi Bob,

I can't think of any good reasons to hear anything from the connector,
and only a couple of not so good ones.  A current high enough to make a
spark, or some mechanical movement inside the connector.  The output of
the EC2 should either be at ground or a fairly high resistance so no
high current flow from there to ground. The diodes should block flow to
another injector that was still connected, so no current flow there.
I don't think putting a probe in the connector should move anything
enough to make a clicking noise.  I don't know what it could be. 

I'll be looking forward to a report after you get the EC2 back.

Bob W.
