[DML] Frequency Valve and ECM



 My frequency valve is not running.  I have +12V on the red/pink ,  when
I jump red/brown to ground the valve opens.  I think this tells me the
rpm relay and all wiring for the +12 are fine.

I've ordered a dwell meter and should have it in a few days.  In the
meantime it looks like all the ground and other wires seem ok.  The
connector at the ECU looks like a pain.  

I have not pulled it off but it looks like its tough to ring out the
unit while its running at the ECU due to the style of the plug.  Any
tips for this?  I'm assuming I need to check all grounds at the ECU.
Check incoming voltages, check the voltage (or impedance) for the oxygen
sensor wire (what are nominal values?) , and then when I have the meter
check the dwell on the output to the frequency valve.  I assume that the
connector at the ECU pulls straight up and off - no releases or catches?

The easiest next step may be to swap out the ECU itself.  If I stop by
the salvage yard and pick up a $10 unit from a Volvo, is it compatible?
