Neutral input into EEC-IV question.

A question for any control module experts out there, what output from the EEC-IV is altered by the neutral drive switch input. (1990F250,2x4,351w,C6).

The IAC solenoid for air intake, fuel pulse time to the injectors and spark advance to the distributor.

Thanks, thats interesting because I checked out a rudimentary wiring diagram I have and suspected that there could be some tie in with the ignition timing because my neutral switch stopped working around the same time my ignition timing stopped advancing.

I can't find a IAC solenoid on my print, could it be called something else?

yes, a great site for all EFI info. I was first introduced to it in a post by Conanski a few years ago. Great reference for the self test, codes and sensors/actuators and much more.
