5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
On the 88-91 EEC electrical diagram herein, what mean exactly "→ ignition run circuit" and "to ignition switch". (Center of the diagram)
Top left, #30 what mean NDS ?
Top right, what mean " ↓to ignition run"
Thanking you
Hard to tell from that picture and diagram but it looks like a pcm input from the clutch or park switch to allow the computer to start the car. Seems odd because my 93 was different.
