From several posts we know that if secondaries are pinned you will get the CEL.
I've studied this diagram, and every connector, to try and determine what tells the IMRC/PCM the secondaries are fully open.
I'm thinking that with a diode you could send the secondaries open voltage back to the PCM telling it they opened. You could bypass the secondaries all together, or remove them, and even run them pinned with no light.
Thoughts?
