Chrysler Repair: 1996 Sebring Convertible JX, egr solenoid, noise suppressor

Question
The car repeatedly blows the #5 ASD fuse.  I have been tracing the wiring diagrams, so I know that this circuit feeds the fuel injectors, the EGR solenoid, the alternator field coils, the coil pack, the upstream O2 sensor directly and the downstream O2 sensor through the #1 fuse.  All of these components check out individually, but the green/orange wire is grounded at all points, including pin 89 of the ASD relay.  The diagram also shows a "noise suppressor" in the circuit, but I can't find it to test it.  

Here's what's got me scratching my head:  just at the rear of the fuse box under the hood are two large connectors, one black and one gray.  The black one holds the green/orange wire.  When I take it apart, both pin 89 of the ASD relay and the rest of the green/orange wire are no longer grounded.  Both sides of the connector and all of the wires coming from them check out visually.  What could cause the whole circuit to be grounded when this connector is plugged in, but neither end of the circuit is grounded when it is separated?

Answer
did u find that same connector on the wire diagram u have?  if so then U just cut half the wires in half and the prob is on that side. what U do is get the fuse to blow all the time then start by unplugging each part on that circuit then see if it still blows when added power until u get it to the one thing that will not blow it any more  then U know U are in the right wire area or part .
