Well, it must be an optical type device. I hooked the connectors backup and turn on the ignition. The one that is messed up a little bit seemed to act up depending on how pressure was applied to the connector. The other seemed to work rock solid. I went back to the questionable IMRC probing it a little differently and it also worked consistantly. Maybe back to square one and then again maybe not.

BTW, here are the reading as I think they should be.

The signal wire on the radiator side of the engine is Tan and the signal wire on the firewall side is orange. Red is 12Vdc and black naturally ground.

IMRC is activated with vacuum closing the IMRC flaps the voltage is 6.8Vdc
IMRC de-activated (engine rpms above 2900) flaps closed voltage is 1.0Vdc

Incidentally, if the connector is unplugged, the PCM signal wire (orange and tan) voltage floats to 5Vdc probably indicating to the PCM that the valve is in the activated or normal operating position.

Who knows, this might be helpful to someone else down the road.
